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?

>>> s = 'sdsd'

>>> s.upper()

'SDSD'

See String Methods.

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'

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.
