Given below is the code for the function as well code to test the function. PLEASE MAKE SURE INDENTATION IS EXACTLY AS SHOWN IN IMAGE.
Please do rate the answer if it helped. Thank you.

def countHi(s):
   if len(s) < 2:
       return 0

   if s[0:2] == "hi":
       return 1 + countHi(s[2:])
   else:
       return countHi(s[1:])

#testing the function

s = "12hi abc hixyz hi"
print(countHi(s))

Please help me with this python3 assignment. Write an iterative function, count_consonants(), that accepts a string (that can include upper and lowercase characters) and returns the number of consonants in that string. A consonant is defined as any letter in the English alphabet other than the vowels a, e, i, o, u. For example, if you call the function as follows: count_consonants('correct horse battery staple') the function should return 20.

Python3 : Write the function longestRun(s, chars) that takes a possibly-empty string s and a second possibly-empty string of chars. We will say that a character is "good" if it is in the chars string (case insensitively, so "A" and "a" would match). The function should return the length of the longest consecutive run of good characters in the given string s. For example, consider: longestRun("abbcazBbcababb","bz"). This returns 3 (look for "zBb"). Restrictions: for loop, slicing cannot be used, if...
