That's it! Now you know how to convert a string to all lowercase or uppercase letters in Python. But in most applications today, developers use the lowercase comparison approach. Here the words are split and then every word of the intermediate result is made lower-case.
This method returns a new string with all the characters of the original string converted. words 'Dave, Laura, Maddy, Dave, Laura, Maddy, Dave, Laura, Dave' result words.lower().split(', ') Alternatively you can use a list comprehension. To lowercase a string in Python, you can use the lower() method. You can also use this method to check that two strings have the same set of characters. Here words is first made lower-case and then splitis called. You can use it similarly to the lower method like this: text = "hello World!" As you may have guessed, the upper method in Python returns a new string where all the characters are in uppercase. The opposite of lowercase is uppercase, and Python also has a method for that as well. To compare both strings while ignoring their case, you can use the lower method like this: text1 = "HeLLo worLD"īy converting both strings to lowercase, you can correctly check if they have the same characters. Because the cases of these characters are different, text1 is not equal to text2 even though they have the same characters. Text1 has an upper "H" and "W" whereas text2 has a lower "h" and "w".
#Python convert string to lowercase code#
In Python, "Hello World" is not equal to "hello world" because equality is case-sensitive as you can see in the code below: text1 = "Hello World" Examples Example 1: Convert string with a mix of lowercase and uppercase characters to lowercase. Returns: A string with all the cased characters converted to lowercase. Here's how to use the lower method in Python: text = "HellO woRLd!"Ī good use case of the lower method is for comparing strings to evaluate their equality regardless of the case. The following is the syntax for using the string lower () function: string.lower() Parameters: The string lower function does not take any parameters.
Numbers, symbols, are all other non-alphabetical characters remain the same. The lower method of strings returns a new string from the old one with all characters in lowercase. To convert a string to lowercase, you can use the lower method. Logic: The difference between the first character of uppercase and ASCII code of lower case character is 32, We add 32 to upper case letters in order to convert. Python has numerous string methods for modifying strings in different ways. An example is Python.Īn uppercase string has all its characters in capital letters. An example is python.Ī capitalized string has the first letter of each word capitalized, and the remaining letters are in small letters. Python lower() function is an inbuilt string class method that converts. In this article, I'll show you how to convert a string to lowercase in Python.Ī lowercase string has all its characters in small letters. To convert any character into lowercase in Python, we use the built-in lower() function. Strings can be in different formats such as lowercase, capitalized, and uppercase.
