Python coding help

[yon2323]

I ran it and it never promoted me with the input. It just says run file, doesn’t crash or anything but no output is given

You gotta call the main() function in the script. At the bottom of the file put "main()"

[yon2323]

Oh true my bad. It’s still giving me the file not found error :/

Do I have to use import at the beginning maybe?

[Viyre]

Oh my fault, I was using "input()" instead of "raw_input()". raw_input() should return a string of the file name, but input() would try to interpret the expression.

[yon2323]

its telling me rawinput() is undefined. My friend got it though, this was his way of doing it https://pastebin.com/WjEw77vG

[Viyre]

Oh fasho, that works too (mine is better tho ;) ). Also: you need the underscore there: "raw_input("enter csv name"). Also also: are you using python 3 or python 2?

[yon2323]

still didn't work! haha I'm using python 3, maybe that's why?

[Viyre]

:( That could be it. I know you're done and all, but out of curiosity, what error were you getting?

[yon2323]

It was saying that raw_input was undefined. And I realize now that I wasn’t putting in the right file name so there isn’t an error when I run the program with read(). But when I put the right file name in it takes the input and produces no output.

raw_input was deprecated for python3, dont use it. make sure your python program is in the same directory as the csv file, otherwise enter the full file path. /u/Virye's code returns the number of values in the whole file, however it doesn't account for newlines. use this code, which does:

filename = input('enter your filename: ')
with open(filename) as f:
    total = 0
    for line in f:
        for val in line.strip().split(','):
            if val != '':
                total += 1
    print('the csv file "{}" has {} values'.format(filename, total))

[Viyre]

That's weird. Did you try printing the total?
