Here's how to debug something like this:

s = """err = calculateCError()
print('Error is:', err, '%')
َAcc = 100 - err
print('َAccuracy is:',َAcc , '%')"""

print([hex(ord(c)) for c in s])

And sure enough, there are three instances of 0x64E, always appearing before 0x41 (A). In fact, if you look carefully at your A characters, you will notice a faint slanted accent line above the A. This is called Arabic Fatha in Unicode. Here is a 320% zoom from my browser showing it more obviously:
