你能读一下文件中一行开头的空格或制表符吗？

Posted 2021-05-05

所以我一直试图看看我是否能找到文件的标签或空格。我现在使用它，我无法弄清楚我应该如何调用空格或制表符或如何找到它。

file = open("file.txt","r")
    for space in line:
        if line.find("    "):
            print("This is something I want to add to the line",line)
#line in print is the rest of that line that has a tab or spaces in front of the text.

“状态”列中的选项卡我需要找到一种方法来读取它们。一行可能有多个标签。

答案

你正在寻找这样的东西：

file = open("file.txt","r")
    for space in line:
        idx = line.find("    ")
        if idx:
            print("This is something I want to add to the line", idx) 
        # Not sure what you want at the end here, but idx will give you the index

另一答案

您应该使用line.find(" ")查找选项卡
