How to capitalize only the title of each string in the list?

问题

WHOLE QUESTION: Write a function that takes as a parameter a list of strings and returns a list containing the each string capitalized as a title. That is, if the input parameter is ["apple pie", "brownies","chocolate","dulce de leche","eclairs"], your function should return ["Apple Pie", "Brownies","Chocolate","Dulce De Leche","Eclairs"].

My program(UPDATED):

I THINK I GOT MY PROGRAM RUNNING NOW! The problem is when I enter: ["apple pie"] it is returning: ['"Apple Pie"']

def Strings():
  s = []
  strings = input("Please enter a list of strings: ").title()
  List = strings.replace('"','').replace('[','').replace(']','').split(",")
  List = List + s

  return List

def Capitalize(parameter):
  r = []
  for i in parameter:
    r.append(i)

  return r

def main():
  y = Strings()
  x = Capitalize(y)
  print(x)

main()

I am getting an error AttributeError: 'list' object has no attribute 'title' Please help!

回答1:

Just iterate over the name list and then for each name, change the case of first letter only by specifying the index number of first letter. And then add the returned result with the remaining chars then finally append the new name to the already created empty list.

def Strings():

  strings = input("Please enter a list of strings: ")
  List = strings.replace('"','').replace('[','').replace(']','').split(",")


  return List

def Capitalize(parameter):
  r = []
  for i in parameter:
    m = ""
    for j in i.split():
      m += j[0].upper() + j[1:] + " "
    r.append(m.rstrip())  


  return r

def main():
  y = Strings()
  x = Capitalize(y)
  print(x)

main()

import re
strings = input("Please enter a list of strings: ")
List = [re.sub(r'^[A-Za-z]|(?<=\s)[A-Za-z]', lambda m: m.group().upper(), name) for name in strings.replace('"','').replace('[','').replace(']','').split(",")]
print(List)

You're operating on the list, not a element of the list.

 r.title()

This makes no sense.
