languages = ['Swift', 'Python', 'Go', 'C++'] for lang in languages: if lang == 'Go': break print(lang) Run Code Output Swift Python Here, when lang is equal to 'Go', the break statement inside the if condition executes which terminates the loop immediately. This is why Go and...
where the loop is controlled by initializing a variable, setting a loop continuation condition, and defining the iteration step. This structure offers fine control over the loop but can be more verbose compared to Python's approach
One Line for Loop in Python Using List Comprehension with if-else Statement The “If else” with “List comprehension” creates more powerful operations like saving space or fast processing repetitive programs. We can perform multiple operations using a single line for loop conditions of list compre...
