Python provides several ways to read a text file and process its lines sequentially or randomly. The correct method to use depends on the size of the file (large or small) and the ease of desired syntax. In this Python tutorial, we will discuss different approaches based on their clean syn...
text = file.read() ``` 这种方法与上面的方法类似,但使用了`with`语句,它会在代码块执行完毕后自动关闭文件,省去了手动关闭文件的步骤。 3.逐行读取文本文件: ```python with open('filename.txt', 'r') as file: lines = file.readlines() for line in lines: #处理每一行的内容 ``` 这个方法适...
