我遇到问题local variable referenced before assignment
,并且感觉以前没有任何答案有帮助。我可以对此代码有一些具体的建议:
import random
marginalCheck = random.randint(0,1)
print("This is the political campaign simulator")
global popularity
popularity = 50
def unpopularT():
if popularity <= 30 and popularity < 0:
print("You are decreasing in popularity.")
popularityRecover = input("Do you wish to carry on or resign. If this carries on, you are likely to lose to a landslide by your Labour opposition")
if popularityRecover == "resign":
print("You have become an infamous, unpopular politician. You are remembered as a horrible, unkind person")
else:
print("You are hanging by a thread")
elif popularity > 70:
print("You are seriously doing well among your supporters and gaining new ones every day")
else:
print("You are doing fine so far in the campaign")
def campaignT():
leadershipT = input("You are chosen as a candidate by your colleagues in the Tory leadership contest. Do you wish to take an A - Far Right, B - Right, C - Centre, D - Left or E - Far Left stance on the political spectrum")
if leadershipT == "A" or leadershipT == "B":
print("You have been elected as leader of the Tories and leader of the opposition. Now the election campaign starts")
ClassicToryAusterity = input("What do you wish to do about the poor funding in the NHS by the Labour government. A - Do you wish to keep the current program, B - Do you wish to increase funding dramatically and increase taxes, C - Do you propose minor increases with small raises on tax, D - Do you support austere implementations on the Health Service")
if ClassicToryAusterity == "A":
popularity += -5
elif ClassicToryAusterity == "B":
popularity += 5
elif ClassicToryAusterity == "C":
popularity += 2
elif ClassicToryAusterity == "D":
popularity += -10
BedroomTax = input("What do you propose to do about the bedroom tax. A - increase it, B - freeze it, C - Decrease it, D - Scrap it")
if BedroomTax == "A":
popularity += -10
elif BedroomTax == "B":
popularity += -5
elif BedroomTax == "C":
popularity += -1
else:
popularity += 10
unpopularT()
else:
print("The Tory whip dislikes your stance and you have not been voted as leader")
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()
我不明白的是,我将人气作为全局变量引用,但根据shell,它是本地的。
答案 0 :(得分:3)
如果要在函数内使用访问全局变量,则不需要声明任何内容,但如果需要通过任何方式重新赋值,则需要在函数内声明它。例如:
test = 'hello'
def print_test():
print test
def set_test():
global test
test = 'new value'
在你的情况下,你没有在你的函数中声明全局变量popularity
,而你试图重新分配它。
所以在你的情况下:
def unpopularT():
global popularity
# your code
def campaignT():
global popularity
# your code
