打印功能仅显示fi的第一行

Question

我只想逐行读取一个文件，并将每一行附加到一个数组中。我以前做过，没有任何问题，我不知道为什么这次不工作！打印功能只显示文件的第一行！！ 这是我的密码：

keyword_array = []    
with open('local directory\\C0577785c.txt') as my_keywordfile:
        for keyword in my_keywordfile.readline().strip("[]").strip("'").split(","):
         keyword_array.append( keyword.strip().strip("'").lower())
         print(keyword_array)

此外，以下是文件内容的子集：

C0001396    adam attack stokes
C0001396    Adam Stokes Attacks
C0001396    Adam-Stokes Attacks
C0001396    adam-stokes syndrome
C0001396    adams attack stoke
C0001396    adams stoke syndrome
C0001396    adams stokes attack
C0001396    ADAMS STOKES SYNDROME
C0001396    Adams-Stokes
C0001396    Adams-Stokes Syndrome
C0001396    Adams-Stokes; attack
C0001396    attack; Adams-Stokes
C0001396    attack; Stokes-Adams
C0001396    Attacks, Adam-Stokes
C0001396    Attacks, Stokes-Adams
C0001396    morgagni's disease
C0001396    Morgagni-Adam's Stokes syndrome
C0001396    Morgagni-Stokes-Adams

谢谢你

Answer 1

只调用readline（）一次，因此只打印一行。你知道吗

Answer 2

在for循环中，您希望对file对象调用.readlines（）。不是readline（）。readline（）只返回第一行，readlines（）返回可以迭代的行列表。你知道吗

从文档中：

readlines(...) method of _io.TextIOWrapper instance
    Return a list of lines from the stream.

    hint can be specified to control the number of lines read: no more
    lines will be read if the total size (in bytes/characters) of all
    lines so far exceeds hint.

我还建议不要清除for循环声明中的行。如果在for循环中这样做，它会觉得读起来容易一些。你知道吗

# ....
with open('myfile.txt', 'r') as my_file:
    for raw_line in my_file.readlines():
        cleaned_data = raw_line.lower().strip("'")
        #....

Answer 3

使用嵌套循环读取我的\u关键字文件的行。你知道吗

for line in my_keywordfile.readlines():
    for keyword in line.strip("[]").strip("'").split(","):
