当我试图在代码中添加注解时,我发现了这个奇怪的问题。我使用了三引号字符串来注解,但程序崩溃,给出了以下错误:IndentationError: unexpected indent
当我使用#
注解三重引号字符串时,一切正常。有谁知道这个错误背后的原因以及如何修复它?
我的代码:
#This programs show that comments using # rather than """ """
def main():
print("let's do something")
#Try using hashtag to comment this block to get code working
'''
Note following block gives you a non-sense indent error
The next step would be to consider how to get all the words from spam and ham
folder from different directory. My suggestion would be do it twice and then
concentrate two lists
Frist think about the most efficient way
For example, we might need to get rid off the duplicated words in the beginning
The thoughts of writing the algorithem to create the dictionary
Method-1:
1. To append all the list from the email all-together
2. Eliminate those duplicated words
cons: the list might become super large
I Choose method-2 to save the memory
Method-2:
1. kill the duplicated words in each string
2. Only append elements that is not already in the dictionary
Note:
1. In this case, the length of feature actually was determined by the
training cohorts, as we used the different English terms to decide feature
cons: the process time might be super long

var3 = var1 + var2 + (var1*var2)
return var3
wtfRst1 = wtf_python(1,2)
wtfRst2 = wtf_python(3,4)
rstAll = { "wtfRst1" : wtfRst1,
"wtfRst2" : wtfRst2

return(rstAll)

print("wtfRst2 is :\n", mainRst['wtfRst2'])

罪魁祸首:
在函数定义中移动注解:
原因:
由于三引号字符串是有效的pythonexp,因此应该将它们同样处理,即:在函数范围内。
因此:

您应该将三引号字符串的缩进级别向右移动一个标记。
虽然三引号字符串经常用作注解,但它们是普通的Python表达式,因此它们应该遵循语言的语法。

作为注解的三重引号字符串必须是有效的Python字符串。有效的Python字符串必须正确缩进。
Python会看到多行字符串,并对其求值,但由于没有给它分配变量,因此字符串在下一行中被丢弃。

上述解决方案是不正确的。对于那些在Emacs 28中遇到过这个问题的人来说,像我一样花了几个小时为此感到沮丧的人,这个问题是一个已知的bug,并且在emacs 29中得到了修复。
