I need to create a variable using the output of another variable like so: y = 1 G = list((G1, G2, G3, G4, G5, G6, G7, G8, G9)) for x in G: "G" + y = input("Some input here") y += 1 This is in order to change the value of each variable individually in ..
I have written a python program to Calculate the average word length and return the average word length. def stringlength(A: List[str]) -> int: average = sum(len(word) for word in A)/len(A) return average test_list = [‘gfg’, ‘is’, ‘best’, ‘for’, ‘geeks’] print(stringlength(test_list)) Answer: 3.4 I am new to calculating time and space complexitities. I am assuming the ..
