Python supplies a variety of strategies and modules that resolve easy to complicated duties simply and inside fewer strains of code. Python additionally supplies varied strategies for string manipulation that carry out operations on strings. One such methodology is the “string.islower()” methodology which checks whether or not the handed string consists of lowercase letters.
This weblog supplies an in depth information on Python’s “string.islower()” methodology through the next contents:
What’s the Python “string.islower()” Methodology?
In Python, the “string.islower()” methodology is utilized to retrieve the Boolean worth “True” if all of the letters/characters within the string are lowercase and “False” if at the least one letter within the string is uppercase.
Notice: The “string.islower()” methodology checks solely alphabetic characters and doesn’t function numbers, symbols, or areas.
Syntax
Parameters
The “string.islower()” methodology doesn’t settle for/take any parameter worth.
Return Worth
The “string.islower()” methodology is used to retrieve the Boolean worth “True” when the string incorporates all of the lowercase alphabets and returns “False” in any other case.
Instance 1: Making use of the “string.islower()” Methodology to Examine the Lowercase Letters/Characters within the Specified String
The “string.islower()” methodology is used within the beneath code to examine whether or not the characters/letters within the specified string include all of the lowercase letters or not:
print(‘Worth 1: ‘, value1)
print(‘Worth 1 Contains All Lowercase Letters: ‘, value1.islower())
value2 = “python”
print(‘nValue 2: ‘, value2)
print(‘Worth 2 Contains All Lowercase Letters: ‘, value2.islower())
value3 = “Python”
print(‘nValue 3: ‘, value3)
print(‘Worth 3 Contains All Lowercase Letters: ‘, value3.islower())
Within the above code:
-
- The a number of string values containing uppercase, lowercase, and combined (uppercase and lowercase) letters/characters, respectively are initialized within the code.
- The “string.islower()” methodology is then used to retrieve the worth “True” if all of the lowercase letters are discovered within the specified string and retrieve “False” when there’s at the least one uppercase letter within the specified string.
Output
As seen, the result is returned accordingly.
Instance 2: Making use of the “string.islower()” Methodology to Examine the Lowercase Letters/Characters within the Consumer Enter String
The beneath code is used to examine whether or not the user-input string incorporates all of the lowercase letters or not:
value1 = enter()
print(value1.islower())
Within the above code:
-
- The “enter()” operate is used to get the enter from the person and retailer it within the variable named “value1”.
- The related “islower()” methodology checks whether or not the person enter string incorporates all of the lowercase letters.
Output
Right here, it may be implied that the “True” and “False” Boolean values are returned appropriately.
Conclusion
The Python “string.islower()” methodology checks whether or not the string incorporates all of the lowercase letters or not by retrieving the corresponding Boolean values “True” and “False”. This methodology retrieves “True” when all characters within the specified string are lowercase and “False” when there’s at the least one uppercase character within the string. This submit offered an in depth information on Python’s “string.islower()” methodology utilizing quite a few examples.
