Python: Convert a given list of tuples to a list of strings

Python List: Exercise - 187 with Solution

Write a Python program to convert a given list of tuples to a list of strings.

Sample Solution:

Python Code:

def tuples_to_list_str(lst):
    result = [("%s "*len(el)%el).strip() for el in lst]
    return result   
colors = [('red', 'green'), ('black', 'white'), ('orange', 'pink')]
print("Original list of tuples:")
print(colors)
print("\nConvert the said list of tuples to a list of strings:")
print(tuples_to_list_str(colors))
names = [('Laiba','Delacruz'), ('Mali','Stacey','Drummond'), ('Raja','Welch'), ('Saarah','Stone')]
print("\nOriginal list of tuples:")
print(names)
print("\nConvert the said list of tuples to a list of strings:")
print(tuples_to_list_str(names))

Sample Output:

Original list of tuples:
[('red', 'green'), ('black', 'white'), ('orange', 'pink')]

Convert the said list of tuples to a list of strings:
['red green', 'black white', 'orange pink']

Original list of tuples:
[('Laiba', 'Delacruz'), ('Mali', 'Stacey', 'Drummond'), ('Raja', 'Welch'), ('Saarah', 'Stone')]

Convert the said list of tuples to a list of strings:
['Laiba Delacruz', 'Mali Stacey Drummond', 'Raja Welch', 'Saarah Stone']

Python: Tips of the Day

Given a predicate function, fn, and a prop string, this curried function will then take an object to inspect by calling the property and passing it to the predicate:

Example:

def tips_check_prop(fn, prop):
  return lambda obj: fn(obj[prop])
check_age = tips_check_prop(lambda x: x >= 25, 'age')
user = {'name': 'Owen', 'age': 25}

print(check_age(user))

Output:

True
