Python: Matches a string that has an 'a' followed by anything, ending in 'b'

Python Regular Expression: Exercise-9 with Solution

Write a Python program that matches a string that has an 'a' followed by anything, ending in 'b'.

Sample Solution:-

Python Code:

import re
def text_match(text):
        patterns = 'a.*?b$'
        if re.search(patterns,  text):
                return 'Found a match!'
        else:
                return('Not matched!')

print(text_match("aabbbbd"))
print(text_match("aabAbbbc"))
print(text_match("accddbbjjjb"))

Sample Output:

Not matched!                                                                                                  
Not matched!                                                                                                  
Found a match!

Python: Tips of the Day

Creates a dictionary with the same keys as the provided dictionary and values generated by running the provided function for each value

Example:

def tips_map_values(obj, fn):
  ret = {}
  for key in obj.keys():
    ret[key] = fn(obj[key])
  return ret
users = {
  'Owen': { 'user': 'Owen', 'age': 29 },
  'Eddie': { 'user': 'Eddie', 'age': 15 }
}

print(tips_map_values(users, lambda u : u['age'])) # {'Owen': 29, 'Eddie': 15}

Output:

{'Owen': 29, 'Eddie': 15}
