Python program to convert a list into a list of lists using a step value
When it is required to convert a list into a list of lists using a step value, a method is defined that uses a simple iteration, the ‘split’ method and the ‘append’ method.
Example
Below is a demonstration of the same
def convert_my_list(my_list):
my_result = []
for el in my_list:
sub = el.split(', ')
my_result.append(sub)
return(my_result)
my_list = ['peter', 'king', 'charlie']
print("The list is :")
print(my_list)
print("The resultant list is :")
print(convert_my_list(my_list))Output
The list is : ['peter', 'king', 'charlie'] The resultant list is : [['peter'], ['king'], ['charlie']]
