Python程序出现NameError: name 'Roblox' is not defined错误求助

你的代码触发NameError的核心原因是缩进错误，Python依赖缩进划分代码块，错误的缩进会导致变量作用域解析异常。

错误根源 #

定义完全局变量后，print、input以及后续的if语句都被错误缩进，而最后的else没有和if保持同级缩进。这种混乱的缩进会让Python解析时，误以为if语句内的Roblox是未定义的局部变量，即便你在全局作用域已经定义了该变量。

修正后的代码 #

from sys import exit
didlogcorrect = 1
Minecraft = 'Minecraft'
Roblox = 'Roblox'
Exit = 'Exit'
chrome = 'chrome'
print('Welcome To PotatOS')
user_input = input("What would you like to do on PotatOS: ")
if user_input == Roblox:
    print('Unable to connect to wifi Now terminating process')
elif user_input == Exit:
    exit()
elif user_input == chrome:
    print('You open Chrome Thinking What should i do now Maybe youtube idk, Then you close Chrome cause your bored!')
elif user_input == Minecraft:
    print('Crashed, Reason 1, you close it cause your mad it crashed')
else:
    print('PotatOS : BEEERGZ Unable to understand')

修正要点 #

• 移除print、user_input及if语句前多余的缩进，让这些代码回到全局作用域
• 调整else的缩进，使其和前面的if保持同级，确保语法结构完整
