Above you assign a value to i_am_global. Because you have not explicitly declared i_am_global as a global variable, it is automatically defined as being local to the main() function. Therefore, any earlier references to i_am_global (e.g., line 45) will generate an UnboundLocalError. In Python, you can always read a global variable without declaring it to be global, but if you want to create or overwrite a global variable within a function, you must first declare it to be global.
