Python --time 计时小程序

process_start_time = time.time()
print(‘开始数据处理‘)

# process function


print(‘结束数据处理‘)
process_stop_time = time.time()

# 差的时间戳
diff_time = process_stop_time - process_start_time
# 将计算出来的时间戳转换为结构化时间
struct_time = time.gmtime(diff_time)
# 减去时间戳最开始的时间 并格式化输出
print(‘数据处理用了{0}年{1}月{2}日{3}小时{4}分钟{5}秒‘.format(
    struct_time.tm_year - 1970,
