The endswith() method available to string objects determines if a string object ends with a specific string value or not and if it does, the bool value True is returned, else the bool value False is returned.

Signature of endswith() method

endswith(value, start, end)

Parameters	Description
value	This is a string value, which is searched in the invoked string. A non-optional attribute.
start	This is an integer value to specify the index position(zero-based index) to start the search at. An optional attribute.
end	An integer value to specify the index position(one-based index) to end the search at. An optional attribute.

• endswith() example


In the upcoming code, we have a string object initialized to a value Hello World and we are going to check whether this string object ends with specific string values.



# Python - Example of endswith() method.



# Creating a string 
s1 = 'Hello World'


# Printing the value of string 
print('String is : ', s1)


# Checking if the string ends with the value 'ld'
b1 = s1.endswith('ld')

print('Does ', s1 , ' ends with ld ? ', b1)


# Checking if the string ends with the value 'Hello'
b2 = s1.endswith('Hello')

print('Does ', s1 , ' ends with Hello ? ', b2)


# Checking if the string ends with the value 'World'
b3 = s1.endswith('World')

print('Does ', s1 , ' ends with World ? ', b3)


# Checking if the string ends with the value 'Wor'
b3 = s1.endswith('Wor')

print('Does ', s1 , ' ends with Wor ? ', b3)





Output is :




String is :  Hello World
Does  Hello World  ends with ld ?  True
Does  Hello World  ends with Hello ?  False
Does  Hello World  ends with World ?  True
Does  Hello World  ends with Wor ?  False





Program Analysis



• In the first comparison, endswith() method returns true, as the string object Hello World ends with a string value, ld.
• In the second comparison, endswith() method returns true, as string object Hello World does not end with a string value, Hello.
• In the last comparison, endswith() method returns false, as string object Hello World ends with a string World
• In the last comparison, endswith() method returns false, as string object Hello World doesn't end with a string Wor.







• Method endswith() is case-sensitive.


Method endswith() checks for comparison between the string value passed to it and the invoked string object, conforming to the case sensitivity of each letter.



# Python - Example of endswith() method.


# Creating a string 
s1 = 'World Peace'


# Printing the value of string 
print('String is : ', s1)



# Checking if the string ends with the value 'World'
b1 = s1.endswith('eace')

print('Does ', s1 , ' ends with eace ? ' , b1)  



# Checking if the string ends with the value 'world'
b2 = s1.endswith('peace')

print('Does ', s1 , ' ends with peace ? ', b2)



# Checking if the string ends with the value 'WORLD'
b3 = s1.endswith('PEACE')

print('Does ', s1 , ' ends with PEACE ? ', b3)





Output is :




String is :  World Peace
Does  World Peace  ends with eace ?  True
Does  World Peace  ends with peace ?  False
Does  World Peace  ends with PEACE?  False





Program Analysis



In the code above, we have a String object initialized to a value World Peace
• In the first comparison, endswith() method returns true, as the string object ends with eace.
• In the second comparison, endswith() method returns false, as string object does not end with peace i.e. with lower case p.
• In the last comparison, endswith() method returns false, as string object doesn't end with upper case PEACE.

• Another example of endswith() method

In the upcoming example, we are going to call the endswith() with two optional parameters start and end.

# Python - Example of endswith() method.


# Creating a string 
s1 = 'The Sky'



# Checking if the string has a value ' Sky', starting at index 3 and ending at 6
# which is false because the value ' Sky' starts at index 3(zero-based index) but ends at index 7(one-based index) 
b1 = s1.endswith(' Sky', 3, 6)

print(b1)




# Checking if the string has a value 'Sky', starting at index 4 and ending at 7
# which is true because the value 'Sky' starts at index 4 and ends at index 7
b1 = s1.endswith('Sky', 4, 7)
print(b1)




# Checking if the string has a value ' Sky', starting at index 3 and ending at 7
# which is true because the value ' Sky' starts at index 3 and ends at index 7
b1 = s1.endswith(' Sky', 3, 7)

print(b1)  



# Checking if the string ends with the value 'ky', starting at index 5 and ending at 10
# which is true because the value 'ky' ends at the index 5 and ends before or at index 10
b2 = s1.endswith('ky', 5, 10)

print(b2)



# Checking if the string ends with the value 'y', starting at index 2 and ending at index 5
# which is false because the value 'y' does not start at index 2
b3 = s1.endswith('y', 2, 5)
print(b3)

Output is :

False
True
True
True
False
