How does the % operator work in Python?

This simple function emulates Python's % operator... % is more efficient, but this code is a good approximation of what it does. The function takes three variables:

value_list, which contains values to be sequentially inserted into a string template.
string_template, a string containing pre-defined values to be replaced.
replace_string, a string that is replaced in string_template, by a value from value_list.

The function returns string_template, a string with replace_string replaced by values from value_list.

def percent_operator_demo(value_list, string_template, replace_string):
    array_len = len(value_list)
    for i in range(array_len):
        string.replace(string_template, replace_string, str(value_list[i]) ,1 )
    return string_template
