Why doesn't the menu in this Python program function? - python-2.7

Question

I have looked over this code 100 times and I feel like it may be something small that I am missing. Program will allow you to login, and display the menu but after entering your selection it continuously displays the menu again.
import sys
def main():
login = 'yes'
choice = 0
hours = [0] * 7
wages = 0
totalHours = 0
totalWages = 0
print
login = raw_input('Do you want to login?')
while not (login == 'yes' or login == 'no'):
print
print 'Please enter a yes or no'
while login == 'yes':
print
userId = raw_input ('Enter user name:')
passWord = raw_input('Enter password:')
while passWord != userId:
print 'Incorrect Password, please try again.'
passWord = raw_input('Enter password:')
while passWord == userId:
print 'Login Success!'
print
print 'Enter 1 to view upcoming schedule'
print 'Enter 2 to view previous schedule'
print 'Enter 3 to calculate wages due'
print 'Enter 4 to verify clock in/out times'
print
choice = raw_input('Enter 1 to 4 from menu.')
def readFromNext(nextWeek):
inFile = open('nextweek.txt', 'r')
str1 = inFile.read()
print str1
str2 = inFile.read()
print str2
print
inFile.close()
def readFromLast(lastWeek):
inFile = open('lastweek.txt', 'r')
str1 = inFile.read()
print str1
str2 = inFile.read()
print str2
print
inFile.close()
def getHours(hours):
counter = 0
while counter < 7:
hours[counter] = input('Enter hours worked per day')
counter = countr + 1
return hours
def getTotalHours(hours, totalHours):
counter = 0
while counter < 7:
totalHours = totalHours + hours[counter]
counter = counter + 1
return totalHours
def getWages(wages):
wages = input('Enter your hourly wage.')
return wages
def getTotalWages(totalHours, wages):
totalWages = totalHours * wages
print 'Your total pay due is:' , totalWages
return totalWages
def readFromClock(clockHours):
inFile = open('clockhours.txt', 'r')
str1 = inFile.read()
print str1
str2 = inFile.read()
print str2
print
inFile.close()
while choice != '5':
if choice == '1':
readFromNext(nextWeek)
print 'Upcoming schedules'
if choice == '2':
readFromLast(lastWeek)
print 'Previous schedules'
if choice == '3':
hours = getHours(hours)
totalHours = getTotalHours(hours, totalHours)
wages = getWages(wages)
totalWages = gettotalWages(totalHours, wages)
print 'Paycheck calculator'
if choice == '4':
readFromClock(clockHours)
print 'Clock in/out times'
main()

Answer 1

What do you expect it to do? You have added many functions but they appear to be unused. You end up printing the menu over and over again because you are in the loop
while passWord == userId:
...
You have to do something with the choice variable and break out of that loop if you want anything else to happen.
For example:
choice = raw_input('Enter 1 to 4 from menu.')
if choice == 1:
readFromNext(nextWeek)
elif choice == 2:
readFromLast(lastWeek)
elif choice == 3:
getTotalWages(totalHours, wages)
elif choice == 4:
getHours(hours)
Obviously you will need to figure out which function maps to which user input, but currently you are not doing anything with the user's choice, merely asking them to choose over and over again with no control over the termination of the loop.

Answer 2

You are not changing the value of login in your while not loop.
login = 'default'
while not (login == 'yes' or login == 'no'):
print 'Please enter a yes or no'
login = raw_input('Do you want to login?')
... for example. The way you currently have it is never going to end:
while not (login == 'yes' or login == 'no'):
print
print 'Please enter a yes or no'
This is conceptually identical as:
while True:
if login == 'yes' or login == 'no':
break
print
print 'Please enter a yes or no'
So if the login is never changed, it will never end.
