[Python] time 模組的常見應用

獲取當前時間戳

import time
current_timestamp = time.time()
print(current_timestamp)

格式化時間

import time
current_time = time.strftime('%Y-%m-%d %H:%M:%S', time.localtime())
print(current_time)

暫停程式執行一段時間

import time
print("開始操作")
time.sleep(3)  # 暫停 3 秒
print("操作完成")

計算程式執行時間

import time
start_time = time.time()
# 執行一些程式碼
end_time = time.time()
execution_time = end_time - start_time
print("程式執行時間：", execution_time, "秒")

獲取當前日期

import time
current_date = time.strftime('%Y-%m-%d', time.localtime())
print(current_date)

時間字串與時間戳的轉換

import time
# 將時間字串轉換為時間戳
time_string = '2023-06-21 12:34:56'
timestamp = time.mktime(time.strptime(time_string, '%Y-%m-%d %H:%M:%S'))
print(timestamp)
# 將時間戳轉換為時間字串
timestamp = 1674737696.0
time_string = time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(timestamp))
print(time_string)
