Python Global Variable Errors

Question

  global temp
   while True:
       Print("Please enter a text: ")
       text = raw_input()
   if text == temp:
       print("the same value")
   else:
       temp = text
       print(text)

I have this code to check if the user is repeating the same value, but getting below error:

NameError: global name 'temp' is not defined

I don't know why I declare the temp but got this error. Is there any other way to check if user keep on putting the same value?

Answer 1

no need to use use global at all.

temp = ""  # Define empty temp
while True:
    text = raw_input("Please enter a text: ")   #write your print message in raw_input only
    if text == temp:  #compare with temp
        print("the same value")
    else:
        temp = text
        print(text)

Output:

Please enter a text: hi
hi
Please enter a text: hi
the same value
Please enter a text: new
new
Please enter a text: new
the same value
Please enter a text: new
the same value
Please enter a text: hi
hi
