Now, consider some tricks which we can use in competitive programming to decrease the time of making your program 1. If your task requires repeat string n times, you don't have to use cycles like "for" or "while", you may only write: ...
Thus, Python does not have the end keyword, since you can omit stop to achieve the same behavior. Try out the following examples of the slice syntax in NumPy: Python In [1]: import numpy as np In [2]: arr_1 = np.arange(1, 7, 2) In [3]: arr_1[1:] Out[3]: array([3...
We have a closure in Python when: A nested function references a value of its enclosing function and then the enclosing function returns the nested function. def get_multiplier(a): def out(b): return a * b return out >>> multiply_by_3 = get_multiplier(3) >>> multiply_by_3(10) 30...
