Introduction to Python Endswith
Python Endswith is a special kind of conditional statement that can be called when checking a statement or a value that ends with a character mostly a string or any other values which we wanted to check whether that statement has in it at the end. The Endswith statement returns True if our condition is satisfied and return false if our condition is failed to satisfy and the basic structure of the Endswith statement has a value to be checked which the user has to give and additionally there are start and end values which is optional comprises of integers which the user wanted to check inside that condition.
The basic syntax of the Endswith statement has a string or the text followed by Endswith statement and round bracket and inside the bracket, we can specify the value or string we want to check.
string/text.endswith(value, start, end)
Explanation: Start and End are optional values we can specify to narrow down our condition with specific start and end values.
statement = "Hello, Have a great day." x = statement.endswith("day.") print(x)
How does Endswith Works?
In the Endswith statement the suffix we denote as the condition is very important because the Endswith statement reads the entire statement and only when the user denoted suffix exactly matches the condition it returns True otherwise it will fail to check the condition and returns False. We should not forget the special characters, comma and full stop when giving the condition because the Endswith statement also reads such characters in the suffix and if our original statement or string has such characters and we fail to give those in conditions then Endswith condition gives us the boolean output is False.
Examples to Implement Python Endswith
Below are the examples mentioned :
statement = "Hello, Have a great day." a = statement.endswith("day.") b=statement.endswith("day") c=statement.endswith("great day") d=statement.endswith("Hello, Have a great day.") print(a) print(b) print(c) print(d)
Explanation: In the above example, we can see how the Python Endswith works, We have declared a statement called “Hello, Have a great day.” and checked the Endswith statement with four types of conditions. In the condition, we have exactly denoted the last word in the statement “day” along with the full stop we used in our statement so the Endswith statement as expected returns us True.
In the second condition b, we have denoted on the word “day” and did not type in the full stop in the condition so Endswith statement checks and returns as False. In the third condition c, we have denoted an additional word “great” followed by “day” both are the last words in the statement but still, we have failed to denote the full stop in the condition and hence our Endswith statement returns False. In the last condition d, we have typed in the entire statement as it is along with the full stop and hence the Endswith statement identifies it and returns us True.
Let us discuss more the Endswith function with start and end parameters which are the integers that represent the position of the string in our Endswith statement returns False. The conditions with starting and ending points denoted.
statement = "This is a sample string" a = statement.endswith("g",22) b=statement.endswith("g",23) c=statement.endswith("g",14) print(a) print(b) print(c)
Explanation: In this example, we have denoted the start parameter along with our string condition “g”. In our statement “This is a sample string” the “g” we have denoted as the condition is at the last position that is the 22nd position of our statement and when we pass the integer 22 in the starting point we got the condition satisfied and Endswith function returns us True.
In the next condition b, we have passed an integer of 23 which is more than the starting point of the letter “g” of the statement and the total characters starting from 0 is only 22 in our whole statement so there is no character in the position 23 hence Endswith function returns False. In the last condition c, we have denoted a position 14 which is below the starting point of the letter “g” and any position which is less or below our conditional value, the Endswith function returns us with True.
Using the start and end parameters which will give us a better understanding of the Endswith function.
statement = "This is a sample string" a = statement.endswith("s",0,7) b=statement.endswith("s",0,8) c=statement.endswith("a",5,9) print(a) print(b) print(c)
Explanation: In the above example, we have used the same statement and passed different conditions with the start and end parameters. In the first condition, we have passed the string s and integers of 0 and 7 as start and endpoints. The string “s” is in position 6 in the statement and when we give the starting point as 0 and endpoint as which is the start and endpoint of the string “s” our condition is satisfied and hence we get the output as True. In the next condition b, we have passed the start point as 0 and endpoint as 8 which is outside the position of the string “s” hence Endswith function gives us the output as False.
In the 3rd condition c, we have the string “a” which is at the 9th position in the statement and the starting point can be anywhere from 0 to 8 where the string “a” is present and if we pass the starting point greater than 8 which violates the condition since the starting point of “a” is at 8 Endswith functions returns the output as False.
We have discussed in detail about the Endswith function in Python is the definition and the way it works with simple examples for better understanding. We have also discussed with clear examples of the start and end parameters used in the Endswith function so that we can narrow down or specify the condition we wanted to check using the Endswith function. The Endswith function is very helpful in python programming when we wanted to check for the position of a string by passing our conditions through the Endswith function.
