Python: Separate and print the numbers and their position of a given string

Python Regular Expression: Exercise-29 with Solution

Write a Python program to separate and print the numbers and their position of a given string.

Sample Solution:-

Python Code:

import re
# Input.
text = "The following example creates an ArrayList with a capacity of 50 elements. Four elements are then added to the ArrayList and the ArrayList is trimmed accordingly."

for m in re.finditer("\d+", text):
    print(m.group(0))
    print("Index position:", m.start())
	

Sample Output:

50                                                                                                            
Index position: 62

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}
