每天一点python：正则表达式中的findall方法

举例：使用findall获取所有匹配的正则表达式文本，然后逐一替换。

 A regular expression example: find all matched text using findall()
 """
 import re

 text = "The ADJECTIVE panda walked to the NOUN and then VERB. A nearby NOUN was unaffected by these events. "

 # Match ADJECTIVE,NOUN or VERB. Independent object relative to the text to be matched
 wordRegex = re.compile(r'(ADJECTIVE|NOUN|VERB)')
 # Pass the target text into a method of the regex object
 #  findall(): return a list of all matched texts
 matches = wordRegex.findall(text)
 for match in matches:
     # Get input from command line
     newWord = str(input("Enter a {}:".format(match.lower())))
     # Replace matched text with newWord, repalce only once, for the first one.
     text = text.replace(match, newWord, 1)

 print(text)
