DescriptionA character string is said to has period K If it can be formed by concatenating one or more repetitions of another string of length k. For example, the string "abcabcabcabc" had period 3, since it was formed by 4 repetitions of the string "abc ". It also has periods 6 (both repetitions of "abcabc") and (one repetition of "abcabcabcabc"). Write a program to read a character string and det

Compile a function. When n is an even number, call the function to calculate 1/2 + 1/4 +... + 1/n. When n is an odd number, call the function 1/1 + 1/3 +... + 1/n ., Even number First, write a function whose n is an even number: Def peven (n): s = 0.0 for I in range (2, n + 1.0): s + =/I print 'value:', s Write another function with n as an odd number: Def podd (n): s = 0.0 for I in range (1, n + 1.0):
