在出现引用错误之前调用的 Python 函数？答案

【问题描述】：

我对以下代码有疑问：

#1/usr/bin/env python3
import random
financialPoints = 0
debatePointsT = 0
marginalCheck = random.randint(0,1)
debatePointsTO = 0
Choice = random.randint(0,2)

popularity = 0
name = input("What is your first name")
nameSur = input("What is your surname")

print("This is the political campaign simulator")
chosenParty = input("Choose a party. A - LibDem, B - Labour, C- Tory")

if chosenParty == "C":
    print("You have been elected as a councillor by your fellow peers.")
    marginality = input("They want you to stand as a MP in a seat. Do you want to stand in a safe or marginal seat")
    if marginality == "marginal":
        if marginalCheck == 0:
            print("You have failed to be elected to parliament")
        else:
            print("You are duly elected the MP for your constituency!")
            campaignT()
    else:
        campaignT()





def debateT():

    #My Code
    if marginality == "safe":
          campaignT()


def campaign():
    #My Code
    if elected == True:
           debateT()

它告诉我在引用它之前我已经调用了一个函数，但我需要它在那里以便我运行代码的另一部分，如上所示。在 python 中，我有没有办法让函数并排运行，或者类似的东西？

【问题讨论】：

“我需要它在那里”是什么意思？大部分代码是给你的，你只被允许/期望填写函数体吗？
@Anish，您在底部定义了一个函数 campaign，但在 if-else 块中调用了函数 campaignT。除此之外，将函数放在文件的开头。
我需要它在那里，这样我才能使用变量

标签： python function

【解决方案1】：

函数定义必须在引用它的代码之前。

将debateT() 和campaign() 移至文件顶部。

【解决方案2】：

将您定义的函数移动到文件顶部，例如：

#1/usr/bin/env python3
import random
financialPoints = 0
debatePointsT = 0
marginalCheck = random.randint(0,1)
debatePointsTO = 0
Choice = random.randint(0,2)

def debateT():

#My Code
    if marginality == "safe":
        campaignT()


def campaign():
    #My Code
    if elected == True:
        debateT()

popularity = 0
name = input("What is your first name")
nameSur = input("What is your surname")

print("This is the political campaign simulator")
chosenParty = input("Choose a party. A - LibDem, B - Labour, C- Tory")

if chosenParty == "C":
    print("You have been elected as a councillor by your fellow peers.")
    marginality = input("They want you to stand as a MP in a seat. Do you want to stand in a safe or marginal seat")
    if marginality == "marginal":
        if marginalCheck == 0:
            print("You have failed to be elected to parliament")
        else:
            print("You are duly elected the MP for your constituency!")
            campaignT()
    else:
        campaignT()
