In this tutorial, we will learn about the Python String upper() method with the help of examples.
The upper()
method converts all lowercase characters in a string into uppercase characters and returns it.
Example
message = 'python is fun' # convert message to uppercase print(message.upper()) # Output: PYTHON IS FUN
1. Syntax of String upper()
The syntax of upper()
method is:
string.upper()
2. upper() Parameters
upper()
method doesn’t take any parameters.
3. upper() Return Value
upper()
method returns the uppercase string from the given string. It converts all lowercase characters to uppercase.
If no lowercase characters exist, it returns the original string.
4. Example 1: Convert a string to uppercase
# example string string = "this should be uppercase!" print(string.upper()) # string with numbers # all alphabets should be lowercase string = "Th!s Sh0uLd B3 uPp3rCas3!" print(string.upper())
Output
THIS SHOULD BE UPPERCASE! TH!S SH0ULD B3 UPP3RCAS3!
5. Example 2: How upper() is used in a program?
# first string firstString = "python is awesome!" # second string secondString = "PyThOn Is AwEsOmE!" if(firstString.upper() == secondString.upper()): print("The strings are same.") else: print("The strings are not same.")
Output
The strings are same.
Note: If you want to convert to lowercase string, use lower(). You can also use swapcase() to swap between lowercase to uppercase.
