如何在python中将每个单词的第一个字母大写而不使用.capitalize or.upper or.title

Question

I currently have:

def myTitle(string):
    index = 0
    title = ''
    while index < len(string):
        if string[index] == ' ':
            upper=string[index+1]
            upper = (ord(upper) - 32)
            title = title + ' ' + chr(upper)
        else:
            title = title + string[index]

String is defined as "I like coffee a lot" but title gets returned as "I Llike Ccoffee Aa Llot"

Answer 1

You've just forgotten 3 lines: index+=1 twice and return title

The fixed function looks like this:

def myTitle(string):
    index = 0
    title = ''
    while index < len(string):
        if string[index] == ' ':
            upper=string[index+1]
            upper = (ord(upper) - 32)
            title = title + ' ' + chr(upper)
            index+=1
        else:
            title = title + string[index]
        index+=1
    return title
