This line of code takes a number (num), converts it to a string, and then maps a lambda function to each digit in the string. The lambda function takes each digit, converts it to an integer, raises it to the power of 3, and returns the result. The map function returns a list of the results of the lambda function applied to each digit in the original number.
For example, if num = 123, the code would convert it to the string "123", and then apply the lambda function to each digit in the string:
- The lambda function would take "1", convert it to the integer 1, raise it to the power of 3, and return 1^3 = 1.
- The lambda function would then take "2", convert it to the integer 2, raise it to the power of 3, and return 2^3 = 8.
- Finally, the lambda function would take "3", convert it to the integer 3, raise it to the power of 3, and return 3^3 = 27.
The map function would then return the list [1, 8, 27], which represents the cube of each digit in the original number.
