大写一个字符串

Question

Does anyone know of a really simple way of capitalizing just the first letter of a string, regardless of the capitalization of the rest of the string?

For example:

asimpletest -> Asimpletest
aSimpleTest -> ASimpleTest

I would like to be able to do all string lengths as well.

Answer 1

>>> b = "my name"
>>> b.capitalize()
'My name'
>>> b.title()
'My Name'

Answer 2

@ saua is right, and

s = s[:1].upper() + s[1:]

will work for any string.

Answer 3

What about your_string.title() ?

eg "banana".title() -> Banana

Answer 4

s = s[0].upper() + s[1:]

除了空字符串（当s="" ）时，这应该适用于每个字符串。

Answer 5

this actually gives you a capitalized word, instead of just capitalizing the first letter

cApItAlIzE -> Capitalize

def capitalize(str): 
    return str[:1].upper() + str[1:].lower().......

Answer 6

for capitalize first word;

a="asimpletest"
print a.capitalize()

for make all the string uppercase use the following tip;

print a.upper()

this is the easy one i think.

Answer 7

You can use the str.capitalize() function to do that

In [1]: x = "hello"

In [2]: x.capitalize()
Out[2]: 'Hello'

Hope it helps.

Answer 8

Docs can be found here for string functions https://docs.python.org/2.6/library/string.html#string-functions
Below code capitializes first letter with space as a separtor

s="gf12 23sadasd"
print( string.capwords(s, ' ') )

Gf12 23sadasd

Answer 9

str = str[:].upper()

在我看来，这是最简单的方法
