I am trying to build a raffle system that allows you to choose participants and then print them to the screen. I want to make it cross compatible with python3 and python2. I am having problems with the inputs. The inputs down where it ask you to enter the participant names keep giving me an error:
Traceback (most recent call last):
File "employee-raffle.py", line 20, in <module>
participant_list.append(input("Enter person " + str(len(participant_list) + 1) + ": "))
File "<string>", line 1, in <module>
NameError: name 'test' is not defined
From code:
# Import modules
import time
import random
print("Welcome to the raffle ")
participants = 0
# Checks how many people are participating in the raffle
while True:
try:
participants = int(input("\nHow many people are there in the raffle? \n"))
break
except:
print("Invalid option")
continue
# Creates a list and asks user to input the names of everyone
participant_list = []
while participants > len(participant_list):
participant_list.append(input("Enter person " + str(len(participant_list) + 1) + ": "))
# Chooses a random person
random_participant = participant_list[random.randint(0,len(participant_list ) - 1)]
# Prints the person to the screen
print("AND THE WINNER IS:")
print("3")
time.sleep(1)
print("2")
time.sleep(1)
print("1")
time.sleep(1)
print(random_participant)
It seems to work fine in python 3. I really want it to work with both because I am trying to learn how to make things cross compatible as it is an important programming practice in my opinion.
This blog has some examples of making a python file compatible with both python 3 and 2.
A particular example for taking input that he mentions is :
def printme(s):
sys.stdout.write(str(s))
def get_input(prompt):
if sys.hexversion > 0x03000000:
return input(prompt)
else:
return raw_input(prompt)
