I'm trying to figure out if there's a way to make a small calculation by subtracting a variables number from 4

number_1_raw = random.randrange(1, 1000)
number_1_len = len(number_1_raw)
number_of_zeros = 4 - number_1_len
print("0" * number_of_zeros + number_1_raw)

I wanted the script to give me an answer that ranged from 1-3, however the
code isn't executing properly.

The desired output would be something like this:
0617 or 0071 or 0008, etc.

Please help with this issue, thanks!

You cant call len on an integer.

The len() function returns the number of items in an object.
When the object is a string, the len() function returns the number of
characters in the string.

so what you can do is

number_1_len = len(str(number_1_raw))

str changes int type to string type.

This line number_1_len = len(number_1_raw)  is problem. You are getting an integer value as number_1_len, and it has length of one. This number_1_len is actually the number of zeros that you want

Fist all I need to understands better what are happening...

Fist

number_1_raw = random.randrange(1, 1000)

The random.randrange returns a number, probably int.

Second

number_1_len = len(number_1_raw)

Has a problem, because number_1_raw is an int and len is a function that count the number of elements from an array, an object... but number_1_len isn't... that's an int and len can't count an int element...

Is important you show all which error you're getting... and explain better what you're trying to do...

I think you need:

import random

number_1_raw = random.randrange(1, 1000)
number_1_len = len(str(number_1_raw))
number_of_zeros = 4 - number_1_len
print(number_of_zeros)
result = "0" * number_of_zeros

print(result+str(number_1_raw))

Output

1 # number of zeros
0801

What's wrong with your code

You are trying to find length of an integer number_1_raw which is giving you the error as you need iterables or string to find a length of that object. First convert it into string and then use len on it.

Furthermore, in print statement you need to convert number_1_raw into string so that it can be appended. You can not perform + operation on str and int.
