The code even seems weird-looking because the entire function is placed inside an if statement. The dataclass defines an ATM which has three parameters describing it. The function print_atm_statistics receives a list of atms as a parameter to process them somehow. In the case of a valid par...
Given a nested list of integers, return the sum of all integers in the list weighted by their depth. Each element is either an integer, or a list -- whose elements may also be integers or other lists. Example 1: Given the list [[1,1],2,[1,1]], return 10. (four 1's at dept...
Nested while Loop in Python In Python, The while loop statement repeatedly executes a code block while a particular condition is true. We use w a while loop when number iteration is not fixed. In this section, we will see how to use a while loop inside another while loop. The syntax to...
Inner or Nested classes are not the most commonly used feature in Python. But, it can be a good feature to implement code. The code is straightforward to organize when you use the inner or nested classes. 3. Coding Inner Classes Implementing the inner or nested classes is not difficult. ...
