The upper method

The upper method returns a string in which all characters of the string are in uppercase. We do not specify anything in the method parameter.

Syntax

string.upper()

Example

Let's apply the upper method to the following line:

txt = 'AbcDef' print(txt.upper())

Result of code execution:

'ABCDEF'

Example

Now let's apply the upper method to a string consisting of two words:

txt = 'AbWith DeA' print(txt.upper())

Result of code execution:

'ABWith DEA'
