Any idea on how can I acccess or get the box data (see image) under TI_Binning tab of excel file using python? What module or similar code you can recommend to me? I just need those specifica data and append it on other file such as .txt file.
Getting the data you circled:
import pandas as pd
df = pd.read_excel('yourfilepath', 'TI_Binning', skiprows=2)
df = df[['Number', 'Name']]
To appending to an existing text file:
import numpy as np
with open("filetoappenddata.txt", "ab") as f:
np.savetxt(f, df.values)
More info here on np.savetxt for formats to fit your output need.

I want to read a CSV File (filled in by temperature sensors) by python3.
Reading CSV File into array works fine. Printing a single cell by index fails. Please help for the right line of code.
This is the code.
import sys
import pandas as pd
import numpy as np
import array as ar
#Reading the CSV File
# date;seconds;Time;Aussen-Temp;Ruecklauf;Kessel;Vorlauf;Diff
# 20211019;0;20211019;12,9;24;22,1;24,8;0,800000000000001
# ...
# ... (2800 rows in total)
np = pd.read_csv('/var/log/LM92Temperature_U-20211019.csv',
header=0,
sep=";",
usecols=['date','seconds','Time','Aussen- Temp','Ruecklauf','Kessel','Vorlauf','Diff'])
br = np # works fine
print (br) # works fine - prints whole CSV Table :-) !
#-----------------------------------------------------------
# Now I want to print the element [2] [3] of the two dimensional "CSV" array ... How to manage that ?
print (br [2] [3]) # ... ends up with an error ...
# what is the correct coding needed now, please?
Thanks in advance & Regards
Give the name of the column, not the index:
print(br['Time'][3])
As an aside, you can read your data with only the following, and you may want decimal=',' as well:
import pandas as pd
br = pd.read_csv('/var/log/LM92Temperature_U-20211019.csv', sep=';', decimal=',')
print(br)
**I have some text files & I need to convert that file into excel format. **
Txt_1 ,
Txt_2
*I'm using Python Pandas to do it. But I'm getting output as this *
Converted_excel_file
After converting data is not in proper order
*Code..*
import pandas as pd
my_cols = [str(i) for i in range(20)] # create some row names
df = pd.read_table('TEST_1.txt',
sep='\s+[\s|\r]',
skip_blank_lines=False,
skipinitialspace=True,
names=my_cols,
engine="python")
df.to_excel('Converted_excel_file.xlsx' )
How to Convert Txt file in proper way using Pandas or xlwt ,Openpyxl ??

I tried use capital VIOLENCE,print (c_data['VIOLENCE']),but also failed

can someone tell me how to work it out?
Try the following if your data is small:
with open('crime.csv', 'r') as my_file:
reader = csv.reader(my_file)
rows = list(reader)
print rows[3]
If your data is big, try this:
from itertools import islice
with open('crime.csv', 'r') as my_file:
reader = csv.reader(my_file)
print next(islice(reader, 3, 4))
I use the following code to read a csv file and save it as pandas data frame, but the method always return the iris dataset not my data. What is the problem?
import pandas as pd
a = pd.read_csv(r"D:\data.csv")
print(a)
I have an excel file with string stored in each cell:
rtypl srtyn OCVXZ srtyn
KPLNV KLNWZ bdfgh KLNWZ
xcvwh mvwhd WQKXM mvwhd
GYTR xvnm YTZN YTZN
ngws jklp PLNM jklp
I wanted to read excel file and write it in csv file. As you can see below:
import pandas as np
import csv
df = pd.read_excel(file, encoding='utf-16')
words= open("words.csv",'wb')
wr = csv.writer(words, dialect='excel')
for item in df:
wr.writerow(item)
But it reads the each line in separated alphabet and not as a string.
r,t,y,p,l
I am limited to write file as csv as I gonna use the result in a library that has lots of facility for csv file. Any advice on how I can read all the rows as a string in the cell is appreciated.
You can try the easiest solution:
# -*- coding: utf-8 -*-
import pandas as pd
df = pd.read_excel(file, encoding='utf-16')
df.to_csv('words.csv', encoding='utf-16')
Adding to zipa : If excel has multiple sheets : you can also try
import pandas as pd
df = pd.read_excel(file, 'Sheet1')
df.to_csv('words.csv')
