How do i get these output?

def pair(str):
  count = 0
  for ch in str:
    if ch == 'HLL':
      return "Alice"
    if ch == 'EO':
        return "Bob"
    if ch == "WORL":
        return "Alice"
    if ch == "D":
        return "Bob"
    else:
        return "Hello World"
    print(count)

CodePudding user response：

return is executed before print, which means this method ends before print. print is not reachable in your code.

I don't know that you want to get data type of these output. So, I guess 2 data types and write them here.

1. String

def pair(str):
    count = 0
    result = ''
    for ch in str:
        count  = 1
        if ch == 'HLL':
            result  = "Alice"
        if ch == 'EO':
            result  = "Bob"
        if ch == "WORL":
            result  = "Alice"
        if ch == "D":
            result  = "Bob"
        else:
            result  = "Hello World"
    print(count)
    return result

2. List

def pair(str):
    count = 0
    result = list()
    for ch in str:
        count  = 1
        if ch == 'HLL':
            result.append("Alice")
        if ch == 'EO':
            result.append("Bob")
        if ch == "WORL":
            result.append("Alice")
        if ch == "D":
            result.append("Bob")
        else:
            result.append("Hello World")
    print(count)
    return result

Since return is the code that ends the function(def), for loop is executed only once in your code

• For reference, if the input is a string(str), only one letter is entered in 'ch' in the for loop, so nothing other than D will be identified.
