Question

我刚刚为我的python类完成了我的作业，由于某种原因它无法在CDM中打开。当我处于空闲模式时，它会打开并运行正常。我的朋友代码与我的相同，但他可以在CDM中运行。我的开放和崩溃真的很快。我认为这是我的主要内容，因为如果它是我的其他功能，我将能够通过第一个输入。我和我的朋友查看我的代码并发现没有错，并且混淆了为什么会发生这种情况。因为我们是电脑新手我虽然我会把它带到这里，是的，我的第一个帖子哈哈。有人可以帮我找到我的错误吗？

Answer 1

问题出在def main（）：block之后的缩进中。

你有......

def main(): #main
#The following should be displayed in the read file
#introduction
print('This program reads data from a file, calculate the statistics and then write the             results             to another file.')
print()
print('THIS PROGRAM WILL FIND:')
...

您应该拥有的是在定义main（）方法后缩进的那些print语句。像这样......

def main():
    print('indent after definition is started like this')

这是否是您代码的唯一问题，我不知道。如果您有更多问题，请尝试更改并返回。
