car_rental()hii got a 1 main while loop, inside of it i have 2 while loops, it adds the result of the two inner and if it exceeds 180 days then the main loops runs again and ask the customer gain.
everything is fine untile you reach:
if total_daily_rental_period > 180:
print ("The rental period exceeded 180 days try a lower amount: ")
exceeded_period_invalid = False it eihter ignores it or gets an error depending on indentation level
and cant use other python features, this professor is a moron.

Hello, it gets ignored when the condition isn't met. As for the indentation error, the error traceback message should be pointing you to the spot where the indendation is wrong. Double check alignment of code, it's easy to make an error with indentation. You can also post the full error traceback message (in error tags).

if i input 1 for days and 1 for weeks it adds altogether the loop should stop
if total_daily_rental_period > 180:
exceeded_period_invalid = False
print ("The rental period exceeded 180 days try a lower amount: ")
RE: nested while loop flow help - j.crater - Nov-02-2018
This block of code is not inside the main/outer while loop, it's in the same level, which means it's outside.
The code would be much more readable if you condensed parts of it into functions. Such indendation bugs would be spotted much easier too.

i think i know what i did wrong,
thank j.crater i understood more about indentation.
