How can I convert a string into uppercase in Python?
When I tried to research the problem, I found something about string.ascii_uppercase, but it couldn't solve the problem:
>>> s = 'sdsd' >>> s.ascii_uppercase Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'str' object has no attribute 'ascii_uppercase' See How do I lowercase a string in Python? for the opposite.
title(), 'abc def'.title() will give you Abc Def
.upper() and .lower() functions do not modify the original str i.e. use s = s.upper() for effective resultsTo get upper case version of a string you can use str.upper:
s = 'sdsd' s.upper() #=> 'SDSD' On the other hand string.ascii_uppercase is a string containing all ASCII letters in upper case:
import string string.ascii_uppercase #=> 'ABCDEFGHIJKLMNOPQRSTUVWXYZ' to make the string upper case -- just simply type
s.upper() simple and easy! you can do the same to make it lower too
s.lower() etc.
s = 'sdsd' print (s.upper()) upper = raw_input('type in something lowercase.') lower = raw_input('type in the same thing caps lock.') print upper.upper() print lower.lower() 
for making uppercase from lowercase to upper just use
"string".upper() where "string" is your string that you want to convert uppercase
for this question concern it will like this:
s.upper() for making lowercase from uppercase string just use
"string".lower() where "string" is your string that you want to convert lowercase
for this question concern it will like this:
s.lower() If you want to make your whole string variable use
s="sadf" # sadf s=s.upper() # SADF For questions on simple string manipulation the dir built-in function comes in handy. It gives you, among others, a list of methods of the argument, e.g., dir(s) returns a list containing upper.
For converting the string into uppercase
s = 'capital letters' s.upper() >>> 'CAPITAL LETTERS' For converting only first letter of each word into capital in a sentence
s = 'this is a sentence' str.title(s) >>> 'This Is A Sentence' You can use capitalize() to make the 1st letter uppercase as shown below:
test = "this is a sentence." print(test.capitalize()) # Here Output:
This is a sentence.
