當(dāng)我嘗試向我的代碼添加注釋時，我發(fā)現(xiàn)了這個奇怪的問題。我使用三重引號字符串進(jìn)行注釋，但程序因出現(xiàn)以下錯誤而崩潰：IndentationError: unexpected indent當(dāng)我#用來注釋三重引號字符串時，一切正常。有誰知道這個錯誤背后的原因以及我如何解決它？我的代碼：#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.

移動函數(shù)定義內(nèi)的注釋：
原因：
由于三引號字符串是有效的 python exp，它們應(yīng)該被同樣對待，即在函數(shù)作用域內(nèi)。
因此：
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

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

作為注釋的三重引號字符串必須是有效的 Python 字符串。有效的 Python 字符串必須正確縮進(jìn)。
Python 看到多行字符串，對其進(jìn)行評估，但由于您沒有為其分配變量，因此該字符串在下一行中被丟棄。

您應(yīng)該將三引號字符串的縮進(jìn)級別向右推一個標(biāo)簽。
雖然三引號字符串經(jīng)常被用作注釋，但它們是普通的 Python 表達(dá)式，因此它們應(yīng)該遵循語言的語法。
