Jupyter Notebook / Python

Question

我遇到了麻烦，为什么我得到这个错误。我希望在这个问题上有任何帮助。

happyList = []
sadList = []

exclude = string.punctuation

happy_file = open("happy.txt", "r")
for word in happy_file:
    word = ''.join(ch for ch in word if ch not in exclude)
    happyList.append(word.strip().lower())
happy_file.close()

错误：

    happyList.append(word.strip().lower())
            ^
SyntaxError: invalid syntax

Answer 1

要循环文件happy_file，请尝试使用"with“上下文管理器，以确保正确读取。

happyList = []
with open('happy-file.txt') as f: 
    input_lines = f.readlines() 
    for i in input_lines: 
       # -- do your processing for each input_line
       happyList.append( ... )

Answer 2

for word in happy_file:
    word = ''.join(ch for ch in word if ch not in exclude)
    happyList.append(word.strip().lower())

当你将大小写结果赋值给'word‘时，试着把它也放进去。我不记得具体是什么时候，但我遇到过类似的问题，当时我忘了给出一个类似的任务的else案例。

如果它起作用了，请告诉我。
