使用正则表达式从字符串块中解析日期和时间

(\d{4})-(\d{2})-(\d{2})\s+(\d{2}):(\d{2}):(\d{2})

import re

# 构造正则表达式对象
pattern = re.compile(r'(\d{4})-(\d{2})-(\d{2})\s+(\d{2}):(\d{2}):(\d{2})')

# 待匹配的字符串块
text = "Today is 2022-01-01 10:30:00"

# 匹配字符串
match = pattern.search(text)

if match:
    # 提取匹配结果
    year = match.group(1)
    month = match.group(2)
    day = match.group(3)
    hour = match.group(4)
    minute = match.group(5)
    second = match.group(6)
    
    print(f"Year: {year}")
    print(f"Month: {month}")
    print(f"Day: {day}")
    print(f"Hour: {hour}")
    print(f"Minute: {minute}")
    print(f"Second: {second}")
else:
    print("No match found.")

Year: 2022
Month: 01
Day: 01
Hour: 10
Minute: 30
Second: 00
