How to change a string into uppercase
PythonStringUppercasePython Problem Overview
I have problem in changing a string into uppercase with Python. In my research, I got string.ascii_uppercase
but it doesn't work.
The following code:
>>s = 'sdsd'
>>s.ascii_uppercase
Gives this error message:
Traceback (most recent call last):
File "<console>", line 1, in <module>
AttributeError: 'str' object has no attribute 'ascii_uppercase'
My question is: how can I convert a string into uppercase in Python?
Python Solutions
Solution 1 - Python
Solution 2 - Python
To 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'
Solution 3 - Python
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.
Solution 4 - Python
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()
Solution 5 - Python
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
Solution 6 - Python
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
.
Solution 7 - Python
For converting first letter of each word into capital in a sentence
s = 'this is a sentence'
str.title(s)
>>> 'This Is A Sentence'
