NumPy: Split a given text into lines and split the single line into array values

NumPy String: Exercise-22 with Solution

Write a NumPy program to split a given text into lines and split the single line into array values.

Sample text:
01 V Debby Pramod
02 V Artemiy Ellie
03 V Baptist Kamal
04 V Lavanya Davide
05 V Fulton Antwan
06 V Euanthe Sandeep
07 V Endzela Sanda
08 V Victoire Waman
09 V Briar Nur
10 V Rose Lykos

Sample Solution:

Python Code:

import numpy as np 
student = """01	V	Debby Pramod
02	V	Artemiy Ellie
03	V	Baptist Kamal
04	V	Lavanya Davide
05	V	Fulton Antwan
06	V	Euanthe Sandeep
07	V	Endzela Sanda
08	V	Victoire Waman
09	V	Briar Nur
10	V	Rose Lykos"""

print("Original text:") 
print(student)
text_lines = student.splitlines()
text_lines = [r.split('\t') for r in text_lines]
result = np.array(text_lines, dtype=np.str)
print("\nArray from the said text:")
print(result)

Sample Output:

Original text:
01	V	Debby Pramod
02	V	Artemiy Ellie
03	V	Baptist Kamal
04	V	Lavanya Davide
05	V	Fulton Antwan
06	V	Euanthe Sandeep
07	V	Endzela Sanda
08	V	Victoire Waman
09	V	Briar Nur
10	V	Rose Lykos

Array from the said text:
[['01' 'V' 'Debby Pramod']
 ['02' 'V' 'Artemiy Ellie']
 ['03' 'V' 'Baptist Kamal']
 ['04' 'V' 'Lavanya Davide']
 ['05' 'V' 'Fulton Antwan']
 ['06' 'V' 'Euanthe Sandeep']
 ['07' 'V' 'Endzela Sanda']
 ['08' 'V' 'Victoire Waman']
 ['09' 'V' 'Briar Nur']
 ['10' 'V' 'Rose Lykos']]

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}
