I'm new to python and need help with this issue. I'm trying to make a program that can just take a string and replace $foo$ with a given string, s. Then you could convert that to a function. Then you could generalize it to handle multiple variables.

Question

def variable_subsitution(text, dic): 

        for x, y in dic.items(): 

                text = text.replace(x,y) 

                return text

variable="Michael"

txt=variable_subsitution("Michaek","Michael")

Traceback (most recent call last):

  File "vend.py", line 7, in <module>

    txt=variable_subsitution("Michaek","Michael")

  File "vend.py", line 2, in variable_subsitution

    for x, y in dic.items():

AttributeError: 'str' object has no attribute 'items'
