def num_digits(n):
count = 0
while n:
count = count + 1
n = n / 10
return count
This is a function that basically says how many digits are in a
number. For example,
>>>print num_digits(44)
2
>>>print num_digits(7654)
4
This function counts the number of decimal digits

I've recently started to program. Python is my first language, so I'm
a complete beginner. I've been trying to call python scripts from the
command line by entering this command into it:
>>>python test.py
But it gives me this error message:
>>>python test.py
File "", line 1
python test.py
