Write Operation Result In Python

Question

I can successfully read from a file. However, I can't get an operation results to write.

For ex.:

i edited to include the full code with a recommended change

if 5:
 from pathlib import Path
 a = Path(r"C:\Users\l\Desktop\a.txt").read_text()
 a = int(a)
 qqa = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ`~'
 def x(qqc, qqd):
   qqe = []
   while qqc > 0:
     qqf = qqc % qqd
     qqe.append(qqf)
     qqc = qqc // qqd
   qqg = []
   while qqe:
     qqg.append(qqa[qqe.pop()])
   return ''.join(qqg)
 b = open(r"C:\Users\l\Desktop\b.txt","w")
 b.write(str(x(a,12)))

To explain this:

a.txt contains only the string “24” (excluding the quotes)
x is a base-10 to base-_ conversion operation
“12” is the base

I don't want the write operation to write the literal operation “x(a,12)” (excluding the quotes).

I want the write operation to write the result “20” (excluding the quotes). (“24” in base-12 is “20”.)

How can I get this to work properly in Python 3?

The actual contents of your x() function would appear to be the single most important detail to your question - yet you have chosen to omit it completely. Or is the actual question how to write that function? — jasonharper

As I understand you are getting TypeError: write() argument must be str, not int All you have to do is cast the int to str b.write(str(x(a,12)))

· i tried this, but it just prints "2" in the console · i edited my post to include your recommendation in my code · also, here's a quick video of me doing the whole process: dropbox.com/s/13v7niqlb67y4k6/python.mp4?dl=0

@abcjme, 2 is the expected result of the .write() call, which returns the number of characters that were written. Have you actually looked at the file, to see if the right two characters were written to it?

write() argument must be a string, so in a simple way:

b.write(str(x(a,12)))
