Python Lowercase String


Hey learner, In these topics we will learn about python lowercase string. In python programming, when the letter of the sentence are in uppercase for these conversions from uppercase to lowercase lower() method is used.

Python Lowercase String

lower() method is used to convert the uppercase characters into lowercase characters. The syntax of python lowercase string is:

Syntax : string.lower()
  • Parameters: Lower() method doesn’t take any parameter.
  • Return Value: lower() method return the string value, which is converted all the uppercase string into the lowercase string.

And for capitalization of the first letter is of the sentence, use capitalize() method. The syntax of Capitalization of the first letter of the string is:

Example For Python Lowercase String

Example 1: for all string in uppercase

Python lowercase string

Code

#string with upper case
string = 'TECHNOELEARN IS A LEARNING SITE'

#convert into lowercase
string.lower()
Output : technoelearn is a learning site

In the above program, the string is ‘TECHNOELEARN IS A LEARNING SITE’. By using the lower() method, all string which is in uppercase is converted into lower case. As you can see in the output of the program ‘technoelearn is a learning site’. So, you can easily convert from uppercase character into a lowercase character by using lower() method.


Example 1: for some string are in uppercase and with number.

Python lowercase string

Code

#string with upper case
string = 'The age of Alina is 30 year'

#convert into lowercase
string.lower()
Output : the age of alina is 30 year

In example 2, The program is converting all uppercase characters into lowercase characters. As you can see in the program, the string is ‘The age of Alina is 30 year’ by using lower() method all the uppercase letter are converted into the lowercase letter and the number are same.

islower() Method:

islower() method is used to check the string is in lowercase or not. It returns only true or false. If the string is in lowercase then the islower() method returns true and if the string is in uppercase then return false. And to check the string are in uppercase use isupper() method. The syntax of islower() method is:

Syntax : string.islower()

Example with some uppercase letter:


python islower 1

Code

#take a string
string = 'Technoelearn'

#check the string are in lowercase!
string.islower()
Output : False

In the above islower() program, the string variable take a string ‘Technoelearn’. In which some letter are in uppercase, so by that the islower() method return False.

Example with all lowercase letter:

python islower 2

Code

#take a string
string = 'technoelearn'

#check the string are in lowercase!
string.islower()
Output : True

In the above islower() program the string take ‘technoelearn’. which are in lower character. so is checking the string then islower() method return true.
