【问题描述】:
我正在尝试构建一个抽奖系统,允许您选择参与者,然后将其打印到屏幕上。我想让它与python3和python2交叉兼容。我的输入有问题。它要求您输入参与者姓名的输入一直给我一个错误:
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
来自代码:
# 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)
它似乎在 python 3 中运行良好。我真的希望它能够与两者一起使用,因为我正在尝试学习如何使事物交叉兼容,因为在我看来这是一个重要的编程实践。
【问题讨论】:
-
输入在 Python 2 和 3 中不是同一个函数。
