How to make global list inside function - CHANKC - Nov-25-2020
from output import welcome, more, byebye, summary, invalid, emptylist, close
def food():
global choice
x = 1
while x > 0 and x <= 15:
try:
more()
x = int(input("Enter your choice: "))
choice.append(x)
except:
invalid()
else:
choice.remove(20)
if len(choice) == 0:
emptylist()
else:
choice.sort()
print ("This is your selection:",choice)
close()
print(choice)the code is shown above but I can't do "print(choice)"
RE: How to make global list inside function - Larz60+ - Nov-25-2020
you need to indent lines 1 and 19
you should avoid using globals, instead, return choice.
example:
def food():
x = 1
while x > 0 and x <= 15:
try:
more()
x = int(input("Enter your choice: "))
choice.append(x)
except:
invalid()
else:
choice.remove(20)
if len(choice) == 0:
emptylist()
else:
choice.sort()
print ("This is your selection:",choice)
close()
return choice
print(food())
RE: How to make global list inside function - CHANKC - Nov-25-2020
Alright. Thank you so much but the actual problem is as below:
#main Module
from output import menu
from userinput import userinfo, orders, food
menu()
userinfo()
orders()
print (choice)
#userinput Module
from output import welcome, more, byebye, summary, invalid, emptylist, close
def userinfo():
x = input("Enter your name: ").title()
y = input("Enter your phone number: ")
a = welcome(x)
choice = []
def orders():
order = int(input("Enter your choice: "))
while order >= 0:
try:
if order == 0:
byebye()
order = -1
elif order >= 1 and order <= 15:
choice.append(order)
food()
order = -1
elif order == 16:
summary()
order = -1
elif order >= 17:
emptylist()
order = int(input("Enter your choice: "))
except:
invalid()
def food():
x = 1
while x > 0 and x <= 15:
if x > 0 and x <= 15:
more()
x = int(input("Anymore? "))
choice.append(x)
else:
invalid()
else:
choice.remove(20)
if len(choice) == 0:
emptylist()
else:
choice.sort()
close()
print ("This is your selection:",choice)
#output Module
#Order Menu
def menu():
print (

Line 10, try:
print(userinput.choice)
RE: How to make global list inside function - CHANKC - Nov-25-2020
Nope. It is still error
#Main Module from output import menu from userinput import userinfo, orders, food menu() userinfo() orders() print(userinput.choice)
Error:Traceback (most recent call last):
File "C:\Users\Owner\Desktop\Python Assignment\main.py", line 13, in <module>
print(userinput.choice)
NameError: name 'userinput' is not defined
RE: How to make global list inside function - perfringo - Nov-25-2020
I know nothing about the code above but indeed in this snippet there is no
userinput defined. from userinput import userinfo, orders, foodMaybe you should import from userinput also choice?
RE: How to make global list inside function - CHANKC - Nov-26-2020
It is solved with import choice from userinput. Thank you so much.
