Python – 元组列表中的时间字符串到秒

给定分钟字符串，转换为元组列表中的总秒数。

Input : test_list = [(“5:12”, “9:45”), (“12:34”, ), (“10:40”, )]
Output : [(312, 585), (754, ), (640, )]
Explanation : 5 * 60 + 12 = 312 for 5:12.

Input : test_list = [(“5:12”, “9:45”)]
Output : [(312, 585)]
Explanation : 5 * 60 + 12 = 312 for 5:12.

编程需要懂一点英语

方法：使用循环+拆分（）

在此，我们使用 split() 分隔分钟和秒组件，并执行数学计算以将值转换为所需的秒数，使用 int() 将字符串转换为整数。

Python3

# Python3 code to demonstrate working of 
# Time Strings to Seconds in Tuple List
# Using loop + split()
  
# initializing list
test_list = [("5:12", "9:45"), ("12:34", "4:50"), ("10:40", )]
  
# printing original list
print("The original list is : " + str(test_list))
  
  
res = []
for sub in test_list:
    tup = tuple()
      
    # iterating each tuple
    for ele in sub:
          
        # perform conversion
        min, sec = ele.split(":")
        secs = 60 * int(min) + int(sec)
        tup += (secs, )
    res.append(tup)
  
# printing result 
print("The corresponding seconds : " + str(res))

输出

The original list is : [('5:12', '9:45'), ('12:34', '4:50'), ('10:40', )]
The corresponding seconds : [(312, 585), (754, 290), (640, )]
