How to read multi-line content of a file in python

pythonYou can use theopen()function to open the file, and use thereadlines()method to read multiple lines of the file.

Here is an example:

# 打开文件 file = open('文件路径', 'r') # 读取文件的多行内容 lines = file.readlines() # 关闭文件 file.close() # 打印每一行内容 for line in lines: print(line)

In this example, first use theopen()function to open the specified file, and specify the mode as'r', which means read-only. Then use thereadlines()method to read multiple lines of the file and return a list containing the contents of all lines. Finally, useforto loop through the list and print the contents of each line.
