How can I make it where it will print the longest name/string that was inputed by the user

问题

def myNames():
    names = []
    while True:
        a = input("Enter Name: ")
        if a != "done":
            names.append(a)
        elif a == "done":
            return names

def all_lengths(myNames):
  num_of_strings = len(myNames)
  total_size = 0
  for item in myNames:
     total_size += len(item)
  ave_size = float(total_size) / float(num_of_strings)
  print(ave_size)

all_lengths(myNames())

def longestWord(myNames): 
    count = 0
    for i in myNames:
        if len(i) > count: 
            count = len(i)
            word = I
            print ("the longest string is ", word)

how can I make it print the longest name that was inputted by the user for example: out of Samantha and John it would say that Samantha was the longest name

回答1:

longestName = ""
for name in myNames:
    if len(name) > len(longestName):
        longestName = name
        
print("The longest name is", longestName)

This will check the length of each username, and if the name of that username is longer than the current longest username, it will replace it.

You already have the function for it. Just need to call the function longestWord().

Write longestWord(myNames()) at the end of the program. Right after,

def longestWord(myNames): 
    count = 0
    for i in myNames:
        if len(i) > count: 
            count = len(i)
            word = i    # Need to type I in lower case
            print ("the longest string is ", word)

Update: Since, you don't want the function to ask for names again, you can move the function calling longestWord()inside the above function where it calculates average, with the parameter as myNames i.e.

def myNames():
    names = []
    while True:
        a = input("Enter Name: ")
        if a != "done":
            names.append(a)
        elif a == "done":
            return names

def longestWord(myNames): 
    count = 0
    for i in myNames:
        if len(i) > count: 
            count = len(i)
            word = i
            print ("the longest string is ", word)

def all_lengths(myNames):
  num_of_strings = len(myNames)
  total_size = 0
  for item in myNames:
     total_size += len(item)
  ave_size = float(total_size) / float(num_of_strings)
  print(ave_size)
  longestWord(myNames) # Calling the function with already given names
  
all_lengths(myNames())
