Python: Casts the provided value as a list if it's not one
Python List: Exercise - 266 with Solution
Write a Python program to cast the provided value as a list if it's not one.
- Use isinstance() to check if the given value is enumerable.
- Return it by using list() or encapsulated in a list accordingly.
Sample Solution:
Python Code:
def cast_list(val):
return list(val) if isinstance(val, (tuple, list, set, dict)) else [val]
d1 = [1]
print(type(d1))
print(cast_list(d1))
d2 = ('Red', 'Green')
print(type(d2))
print(cast_list(d2))
d3 = {'Red', 'Green'}
print(type(d3))
print(cast_list(d3))
d4 = {1: 'Red', 2: 'Green', 3: 'Black'}
print(type(d4))
print(cast_list(d4))
Sample Output:
<class 'list'> [1] <class 'tuple'> ['Red', 'Green'] <class 'set'> ['Green', 'Red'] <class 'dict'> [1, 2, 3]
