Python: Cannot Create Zip File - python-3.x

I simply copy-and-pasted this code from a Python tutorial website, but the code won't work. What's missing? I am using version 3.4.3. Thank you.
import zipfile
# Create zip file
print("Creating zip archive")
zf = zipfile.ZipFile("python_zip_file.zip", mode = "w")
try:
# Add file to our zip
zf.write("zippy2.py")
finally:
print("closing")
zf.close()
Traceback (most recent call last):
File "/Users/Cindy/Documents/Python/Zip.py", line 9, in <module>
zf.write("zippy2.py")
File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/zipfile.py", line 1326, in write
st = os.stat(filename)
FileNotFoundError: [Errno 2] No such file or directory: 'zippy2.py'

# Add file to our zip
zf.write("zippy2.py")
You should have a file named zippy2.py in the folder.
Since you just copied the code, you might not have the file that was mentioned in the code. create file
zippy2.py in the same folder and check.

Try learning with this..
#!/usr/bin/env python
import zipfile
print("Creating zip archive")
zip = zipfile.ZipFile(‘Archive.zip’, ‘w’) #Archive is the name of the zip file
zip.write(‘file.txt’) #file.txt should be in the current working directory
zip.write(‘file1.txt’) #file1.txt too
zip.close()

FileNotFoundError in unzipping python file

I need to automate some boring stuff , one of such is unzipping all zip file in the current directory
this is my code:
import os
import zipfile
directory = 'D:\\Python ds and alg by mostafa'
for file in os.listdir(directory):
if file.endswith('.zip'):
zipfile.ZipFile(file).extractall(directory)
however when i run this code I have this error:
Traceback (most recent call last):
File "D:/Python Automation Files/extract_zip_files.py", line 7, in <module>
zipfile.ZipFile(file).extractall(directory)
File "C:\Python310\lib\zipfile.py", line 1247, in __init__
self.fp = io.open(file, filemode)
FileNotFoundError: [Errno 2] No such file or directory: '08_Logical_and_physical_Data_Structures.zip'
The problem seems to be that you try to extract the file '08_Logical_and_physical_Data_Structures.zip' which is not located in the same folder as your script (because its in your directory you defined). So you find it while you search for it (because here you search in the correct directory) but in the line where you try to extract it you dont tell python to extract the file which is located in the directory. So it should work if you change your code to:
import os
import zipfile
directory = 'D:\\Python ds and alg by mostafa'
for file in os.listdir(directory):
if file.endswith('.zip'):
zipfile.ZipFile(directory + file).extractall(directory)
or to be safe you could use os.path.join(directory, file)
Edit: because I just saw it. You try to extract the file:
D:/Python Automation Files/08_Logical_and_physical_Data_Structures.zip
but your code should extract:
D:\\Python ds and alg by mostafa\\08_Logical_and_physical_Data_Structures.zip

Issue while trying to read a text file in databricks using Local File API's rather than Spark API

I'm trying to read a small txt file which is added as a table to the default db on Databricks. While trying to read the file via Local File API, I get a FileNotFoundError, but I'm able to read the same file as Spark RDD using SparkContext.
Please find the code below:
with open("/FileStore/tables/boringwords.txt", "r") as f_read:
for line in f_read:
print(line)
This gives me the error:
FileNotFoundError Traceback (most recent call last)
<command-2618449717515592> in <module>
----> 1 with open("dbfs:/FileStore/tables/boringwords.txt", "r") as f_read:
2 for line in f_read:
3 print(line)
FileNotFoundError: [Errno 2] No such file or directory: 'dbfs:/FileStore/tables/boringwords.txt'
Where as, I have no problem reading the file using SparkContext:
boring_words = sc.textFile("/FileStore/tables/boringwords.txt")
set(i.strip() for i in boring_words.collect())
And as expected, I get the result for the above block of code:
Out[4]: {'mad',
'mobile',
'filename',
'circle',
'cookies',
'immigration',
'anticipated',
'editorials',
'review'}
I was also referring to the DBFS documentation here to understand the Local File API's limitations but of no lead on the issue.
Any help would be greatly appreciated. Thanks!
The problem is that you're using the open function that works only with local files, and doesn't know anything about DBFS, or other file systems. To get this working, you need to use DBFS local file API and append the /dbfs prefix to file path: /dbfs/FileStore/....:
with open("/dbfs/FileStore/tables/boringwords.txt", "r") as f_read:
for line in f_read:
print(line)
Alternatively you can simply use the built-in csv method:
df = spark.read.csv("dbfs:/FileStore/tables/boringwords.txt")
Alternatively we can use dbutils
files = dbutils.fs.ls('/FileStore/tables/')
li = []
for fi in files:
print(fi.path)

FileNotFoundError while using crontab to run Python script

I'm totally lost here. I'm trying to create a scheduler to run python script on my Mac, but I'm getting the following error:
Traceback (most recent call last):
File "/Users/Root/Desktop/Project/Data/script.py", line 148, in <module>
run(
File "/Users/Root/Desktop/Project/Data/script.py", line 121, in run
config = get_config("config")
File "/Users/Root/Desktop/Project/Data/config/__init__.py", line 3, in get_config
with open(f"config/{config_type}.json", "r") as file:
FileNotFoundError: [Errno 2] No such file or directory: 'config/config.json'
So crontab convinces me that there is no such file or a directory, which is not true. I can run my script manually without errors.
My crontab is:
00 19 21 1-12 * /Library/Frameworks/Python.framework/Versions/3.9/bin/python3/ /Users/Root/Desktop/Project/Data/script.py >> /Users/Root/Desktop/Project/Data/cron.txt 2>&1
What am I doing wrong?
I'd be grateful for any help!
And is this possible without changing the relative path to an absolute path? I am aware of this solution
I assume crontab's cwd (Current Working Directory) is not same as where the script is stored.
this would solve your problem:
import os
script_dir = os.path.dirname(os.path.realpath(__file__))
os.chdir(script_dir)
You can get the directory where you script is by calling "os.path.dirname(os.path.realpath(file))"
if you change the current working directory "os.chdir(...dir...)" you can access you config/config.json by relative path,
Otherwise you will have to use a absolute path
Try running this and check your output file:
import os
script_dir = os.path.dirname(os.path.realpath(__file__))
print (os.getcwd())
print(script_dir)
os.chdir(script_dir)
print (os.getcwd())
Try to open with full path to the json file.

Getting Permission Error when trying to write html file

So I'm trying to create a web map, and every time I get to the point of trying to save the map object as a HTML file, I get an error telling me "Permission denied." What could I be doing wrong here?
import folium
>>> map = folium.Map(location=[80, -100])
>>> map
<folium.folium.Map object at 0x00B8AF70>
>>> map.save("Map1.html")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Users\austi\AppData\Local\Programs\Python\Python38-32\lib\site-packages\bran
ca\element.py", line 161, in save
fid = open(outfile, 'wb')
PermissionError: [Errno 13] Permission denied: 'Map1.html'
I think that it is due to the fact that you have not created your HTML file at the right place (in a place where you have the right to do so). You should better use an absolute path (instead of a relative one) for your HTML file name like that :
map.save(r"C:\Users\austi\Map1.html")

Python: FileNotFoundError: [Errno 2] No such file or directory - How to add file to the right directory

I'm new to python! Seen many issues related to this problem but can't find the right way of doing it.
I want to import a picture and change it.
My code is:
from PIL import Image, ImageFilter
import os
root_dir= os.path.dirname(os.path.abspath(r'C:\Users\User\eclipse-workspace\Practice Python CS50 2019\images\Mario.png'))
before = Image.open('Mario.png')
after=before.filter(ImageFilter.BLUR)
after.save("MarioBLUR.png")
The error I'm getting is:
Traceback (most recent call last):
File "C:\Users\User\eclipse-workspace\Practice Python CS50 2019\src\Class 6\blur.py", line 5, in
before = Image.open('Mario.png')
File "C:\Users\User\anaconda3\lib\site-packages\PIL\Image.py", line 2809, in open
fp = builtins.open(filename, "rb")
FileNotFoundError: [Errno 2] No such file or directory: 'Mario.png'
My windows location for this picture is: C:\Users\User\Downloads\Mario.png
My eclipse location is: C:\Users\User\eclipse-workspace\Practice Python\images\Mario.png
How to add this picture to the right directory to make sure I won't have this issue anymore?
You only need the directory path and not the filename in os.path.dirname, for example:
root_dir= os.path.dirname('C:/Users/User/eclipse-workspace/Practice Python CS50 2019/images/')
before = Image.open(root_dir + 'Mario.png')
should work fine
