I created a lottery number generator with Python 3.7. It shows however None at the end of each try. Here's my code.
import random
def lotto_gen():
n = 1
while n < 7:
print(random.randint(1, 45), end='\t')
n += 1
return
for numbers in range(100):
print(lotto_gen())
And the result goes like this:
6 12 42 37 13 44 None
36 31 32 41 4 30 None
20 31 38 42 14 19 None
8 18 29 22 34 29 None
26 34 15 1 20 38 None
10 17 28 35 22 38 None
23 34 42 22 4 43 None
25 16 17 36 17 4 None
44 8 20 1 43 43 None
29 32 9 2 8 5 None
16 44 35 17 42 10 None

I want to remove that None bool type. Can someone tell me how can I edit my code?

Rakesh has given the correct answer, but I would like to explain why your code isn't working. The problem seems to be that for a particular iteration, your code is only able to generate 6 random numbers. Take note, that you have initialized n=1, inside the function lotto_gen() and as the condition for executing the while loop is n<7, the code inside lotto_gen() executes only 6 times.
Now the reason why you receive None at the end is because you are trying to print the value returned by lotto_gen, but take note, that the return field inside your code's function is empty, hence None is returned by the function and hence that gets printed.
So for correcting the code you only need to initialize n as n=0, and to remove the appearance of the none, don't call the function inside a print statement, and create a list which contains the 7 values of each iteration and return it. So, you'll need to modify the code in this manner:
import random
def lotto_gen():
n = 0
a=[]
while n < 7:
a.append(random.randint(1, 45))
n += 1
return a
for numbers in range(100):
print(lotto_gen())
You can use this approach too and my code will execute faster as well! :P

This is one approach.
Ex:
import random
def lotto_gen():
return "\t".join(str(random.randint(1, 45)) for _ in range(6))
for numbers in range(100):
print(lotto_gen())

Patterns in nested for loops

In python I need the output to be the following, I included the image of the output:
enter image description here
1
2 4
3 6 9
4 8 12 16
5 10 15 20 25
6 12 18 24 30 36
7 14 21 28 35 42 49
8 16 24 32 40 48 56 64
9 18 27 36 45 54 63 72 81
I've tried googling the answer but I don't get the exact pattern
Im not sure why you want pattern matching. You can achieve this result with a simple for loop.
for i in range(9):
for j in range(1,i+1):
print((i*j), end=" ")
print("\n")
this should give you the result you want.
_______ = 9
for __, ____ in enumerate(list(range(1,_______+1))):
_____ = f"{____}"
for ___ in range(1,__+1):
_____ = f"{_____} {____*(___+1)}"
print(_____)

A for loop creates more integers than expect in bash

I have two dirs base and to_move. There are 10 files in base, which are named
0 1 2 3 4 5 6 7 8 9, and 3 files, 0 1 2, in to_move. What I want is to move the 3 files in to_move to base, with their names changed to 10 11 12.
Inside the dir to_move, I run the command
tmp=$(ls);for item in ${tmp[#]};do dst=$((item+10));echo $dst $item;done
what I got is
10 0
11 1
12 2
11 1
20 10
21 11
22 12
23 13
24 14

37 27
38 28
13 3
14 4
15 5
16 6
17 7
18 8
19 9
This makes no sense to me, it seems $(($item+10)) has some weird effects on $item.
Why this happens? And how can I modify the command to get this output?
10 0
11 1
12 2

printing a string like a matrix

Trying to let the user input a number, and print a table according to the square of its size. Here's an example.
Size--> 3
0 1 2
3 4 5
6 7 8
Size--> 4
0 1 2 3
4 5 6 7
8 9 10 11
12 13 14 15
Size--> 6
0 1 2 3 4 5
6 7 8 9 10 11
12 13 14 15 16 17
18 19 20 21 22 23
24 25 26 27 28 29
30 31 32 33 34 35
Size--> 9
0 1 2 3 4 5 6 7 8
9 10 11 12 13 14 15 16 17
18 19 20 21 22 23 24 25 26
27 28 29 30 31 32 33 34 35
36 37 38 39 40 41 42 43 44
45 46 47 48 49 50 51 52 53

63 64 65 66 67 68 69 70 71
72 73 74 75 76 77 78 79 80
Here's is the code that i have tried.
length=int(input('Size--> '))
size=length*length
biglist=[]
for i in range(size):
biglist.append(i)
biglist = [str(i) for i in biglist]
for i in range(0, len(biglist), length):
print(' '.join(biglist[i: i+length]))
but instead here's what i got
Size--> 3
0 1 2
3 4 5
6 7 8
Size--> 4
0 1 2 3
4 5 6 7
8 9 10 11
12 13 14 15
Size--> 6
0 1 2 3 4 5
6 7 8 9 10 11
12 13 14 15 16 17
18 19 20 21 22 23
24 25 26 27 28 29
30 31 32 33 34 35
As you can see the rows are not aligned properly like the example.
What's the simplest way of presenting it in a proper alignment? Thx :)
Using .format on string with right aligning.
And strlen is the number of characters required for each number.
length = int(input('Size--> '))
size = length*length
biglist = []
for i in range(size):
biglist.append(i)
biglist = [str(i) for i in biglist]
strlen = len(str(length**2-1))+1
for i in range(0, len(biglist), length):
# print(' '.join(biglist[i: i+length]))
for x in biglist[i: i+length]:
print(f"{x:>{strlen}}", end='')
print()

How to divide 1 column into 5 segments with pandas and python?

I have a list of 1 column and 50 rows.
I want to divide it into 5 segments. And each segment has to become a column of a dataframe. I do not want the NAN to appear (figure2). How can I solve that?
Like this:
df = pd.DataFrame(result_list)
AWA=df[:10]
REM=df[10:20]
S1=df[20:30]
S2=df[30:40]
SWS=df[40:50]
result = pd.concat([AWA, REM, S1, S2, SWS], axis=1)
result
Figure2
You can use numpy's reshape function:
result_list = [i for i in range(50)]
pd.DataFrame(np.reshape(result_list, (10, 5), order='F'))
Out:
0 1 2 3 4
0 0 10 20 30 40
1 1 11 21 31 41
2 2 12 22 32 42
3 3 13 23 33 43
4 4 14 24 34 44
5 5 15 25 35 45
6 6 16 26 36 46
7 7 17 27 37 47
8 8 18 28 38 48
9 9 19 29 39 49

Just some background what does above information means-
1702 calls came back in 0 milliseconds
15036 calls came back in 1 milliseconds
14262 calls came back in 2 milliseconds
etc etc
So to calculate the 95th percentile from the above data, I am using this formula in excel 2010-
=PERCENTILE.EXC(IF(TRANSPOSE(ROW(INDIRECT("1:"&MAX(H$2:H$96))))<=H$2:H$96,A$2:A$96),0.95)
Can anyone help me whether the way I am doing in Excel 2010 is right or not?
I am getting 95th percentile as 10 by using the above scenario.
Thanks for the help.
that's essentially the same question you asked here and the formula I suggested. As per my last comments in that question - that formula should work OK as long as you use CTRL+SHIFT+ENTER correctly. I get 10 as the answer for this example using that formula.
I think you can verify manually that that is indeed the correct answer. If you have a running total in an adjacent column then you can see where the 95th percentile is reached......
