How to use the time module for time processing in Python 2.x

Python is an easy-to-use, powerful programming language with a rich standard library for developers to use. Among them, the time module is an important time processing tool that can help us obtain the current time, perform time conversion, timing and other operations. This article will introduce how to use the time module for time processing in Python 2.x and provide corresponding code examples.

1. Import time module
   Before using the time module, we need to import it first. You can use the following code to import:

import time

2. Get the current time
   Use the time function in the time module to get the current timestamp, that is, starting from midnight on January 1, 1970 seconds. You can use the following code to get the current timestamp:

timestamp = time.time()
print "当前时间戳为：", timestamp

3. Conversion between timestamp and readable time
   Time stamp is more convenient for computers to calculate, but humans are more accustomed to it for reading a human-readable time format. Therefore, we need to convert the timestamp to a readable time, or a readable time to a timestamp. Use the localtime function of the time module to convert a timestamp to local time, and use the strftime function to format local time into a readable time string. The following is a sample code:

# 将时间戳转换为本地时间
local_time = time.localtime(timestamp)
print "本地时间为：", local_time

# 将本地时间格式化为可读时间字符串
readable_time = time.strftime("%Y-%m-%d %H:%M:%S", local_time)
print "可读时间为：", readable_time

4. Delay waiting
   In programming, we sometimes need to add a delay wait in the program to control the execution time interval of the task. The sleep function of the time module can help us implement delay waiting in seconds. The following is a sample code:

print "开始执行任务"
time.sleep(5)  # 延时5秒
print "任务执行完成"

5. Timing function
   Sometimes we need to calculate the time required for the program to run. The clock function of the time module can help us implement the timing function. The following is the sample code:

start_time = time.clock()  # 记录开始时间

# 执行任务
for i in range(1000000):
    pass

end_time = time.clock()  # 记录结束时间

# 计算运行时间
running_time = end_time - start_time
print "程序运行时间为：", running_time, "秒"

In this article, we introduce the method of using the time module for time processing in Python 2.x and provide corresponding code examples. By learning and mastering these methods, we can handle time-related tasks more effectively and improve programming efficiency. I hope this article can be helpful to readers in time processing in Python programming.
