Python核心编程正则表达式练习题1-1 识别后续的字符串:“bat”、“bit”、“but”、“hat”、“hit”或者“hut”

# 1-1 识别后续的字符串:“bat”、“bit”、“but”、“hat”、“hit”或者“hut”。

 import re

 # 正则表达式，|元字符表示选择“或”
 # character = 'bat|bit|but|hat|hit|hut' # 方法一
 # character = '[bh][aiu]t'  # 方法二
 character = '(b|h)(a|i|u)t' # 方法三

 # 测试数据
 data = 'bat'
 data1 = 'bit'
 data2 = 'but'
 data3 = 'hat'
 data4 = 'hit'
 data5 = 'hut'

 # 测试开始
 m = re.match(character, data)
 m1 = re.match(character, data1)
 m2 = re.match(character, data2)
 m3 = re.match(character, data3)
 m4 = re.match(character, data4)
 m5 = re.match(character, data5)

 if m is not None:
     print("data与character匹配成功，结果为:")
     print(m.group())

 if m1 is not None:
     print("data1与character匹配成功，结果为:")
     print(m1.group())

 if m2 is not None:
     print("data2与character匹配成功，结果为:")
     print(m2.group())

 if m3 is not None:
     print("data3与character匹配成功，结果为:")
     print(m3.group())

 if m4 is not None:
     print("data4与character匹配成功，结果为:")
     print(m4.group())

 if m5 is not None:
     print("data5与character匹配成功，结果为:")
     print(m5.group())
