Python正则表达式练习

# 一. 判断字符串是否是全部小写（s1 = 'adkkdk' s2 = 'abc123efg'）
# import re,time
# s1 = 'adkkdk'
# s2 = 'abc123efg'
# if re.findall('[a-z]*',s1):
#     print('s1全部为小写')
# else :
#     print('鬼才知道是不是小写')
# if not re.findall('d*',s2):#如果包含数字就不是全部小写
#     print('s2全部为小写')
# else :
#     print('鬼才知道是不是小写')
# print(time.ctime())

# 二.  首字母缩写词扩充
# 具体示例
# FEMA   Federal Emergency Management Agency
# IRA    Irish Republican Army
# DUP    Democratic Unionist Party
# FDA    Food and Drug Administration
# OLC    Office of Legal Counsel
# 分析
# 缩写词　　FEMA
# 分解为　　F*** E*** M*** A***
# 规律　　  大写字母 + 小写（大于等于1个）+ 空格
# import time,re
# s1 = 'Federal Emergency Management Agency'
# s2 = 'Irish Republican Army'
# s3 = 'Democratic Unionist Party'
# s4 = 'Food and Drug Administration'
# s5 = 'Office of Legal Counsel'
# res = re.split('[^A-Z]+',s1)
# res1 = "".join(res)
# print(res1+'的扩展形式是:
'+s1)
