We learned how the isupper() method is used to check a given string. In this Python tutorial, we looked at how the upper() method is used. Switching between the character cases is a common string operation in Python. This is because the string contains only uppercase letters. Whereas, the second print statement has printed out True. This is because the function found lowercase characters in the string. In the output of our first print statement, the method has returned False. Print(visitor_name002.isupper()) Output: False
If it finds any characters in lowercase it returns False, else it returns True. The isupper() method checks every case-based character. The isupper() method checks every case-based character. Before we do convert a string to uppercase, we might have to check if it is already in uppercase. Print(visitor007.upper()) Output: The Original String:īefore we do convert a string to uppercase, we might have to check if it is already in uppercase. Input: # Python program for upper() function This is because those characters aren’t upper/lower case based. The upper() method does not affect whitespace, numbers or symbols with a string. Secondly, we use Python’s upper() method to convert the visitor007 to uppercase. This variable stores the name of our amusement park visitor.
#CONVERT STRING TO LOWERCASE IN SWIFT CODE#
In the above code snippet, we declare a variable called visitor007. Print(visitor007.upper()) Output: Original String: # upper() function converts string to uppercase Input: # Python program to show the working of the upper() function In the place of string we enter the name of the variable containing the string. The syntax of the method upper() is: string.upper()Īs you can see, the method does not take any parameters. This helps with uniformity in storage and easy readability during the ticket check process. You may want to convert all the names of the visitors to uppercase format before printing them on the ticket. The isupper() method, on the other hand, returns True if all the letters in a string are uppercase.Ī real-life use-case of this function is an amusement park ticketing application. The Python upper() method is used to convert lowercase letters in a string to uppercase. Python facilitates this with the following functions: Or we might have to check if a given string is uppercase or not.
While working with strings, there might be instances where we need to convert lowercase strings to uppercase.
