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

pythonYou can use the open() function to open the file, and use the readlines() 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 the open() function to open the specified file, and specify the mode as 'r', which means read-only. Then use the readlines() method to read multiple lines of the file and return a list containing the contents of all lines. Finally, use for to loop through the list and print the contents of each line.

Please note that after reading the file content, you need to use the close() method to close the file to release system resources. In addition, if the file to be read does not exist, a FileNotFoundError exception will be thrown, so error handling is required in actual use.

Python vs. C  : Learning Curves and Ease of UsePython vs. C : Learning Curves and Ease of UseApr 19, 2025 am 12:20 AM

Python is easier to learn and use, while C is more powerful but complex. 1. Python syntax is concise and suitable for beginners. Dynamic typing and automatic memory management make it easy to use, but may cause runtime errors. 2.C provides low-level control and advanced features, suitable for high-performance applications, but has a high learning threshold and requires manual memory and type safety management.

Python vs. C  : Memory Management and ControlPython vs. C : Memory Management and ControlApr 19, 2025 am 12:17 AM

Python and C have significant differences in memory management and control. 1. Python uses automatic memory management, based on reference counting and garbage collection, simplifying the work of programmers. 2.C requires manual management of memory, providing more control but increasing complexity and error risk. Which language to choose should be based on project requirements and team technology stack.
