Python tutorial 11: Python String Methods - endswith ( ) by Manish Sharma

Key Takeaways

you supernet i am manish from rebellionrider.com and i am back once again with another awesome python tutorial to this tutorial is going to be about another string matter of Python language witches and swears now that we have learned how to check if a string starts with a specified service string or not in the last tutorial it's time to move on and learn how to find out if a string ends with a specified string or not but before that please do not leave without pressing that thumbs up button if you liked the video also this year I'm aiming for one leg subscribers so please subscribe to the channel if you haven't already now let's start off the starts with the second string method in the list of Python programming is ants with as the name suggests using this function we can determine if a string is ending with a specified service string or not let's take a quick look at the syntax of this string method and with the syntax is pretty much the same as the previous string function starts with the method ends with also accepts three parameters let's take a look at those survey string the first parameter is the substring this is a string that will be served in the main string this is the only mandatory parameter in the list start ID X the second parameter is the start index here you have to specify an integer value which will indicate the index number from where the interpreter will start the search of this of a string this is an optional parameter which means if you want you can skip it in case you do not mention the start index then interpreter will start the search from the index 0 which is the default value and ID X the third parameter is the end index similar to start index here also you have to mention an integer value this value will specify the index number on which the interpreter should stop the search once again this is an optional parameter in case you do not mention any value here then the interpreter will keep searching until the mean string ends that's all about the syntax now let's do some examples and learn how this string methods read works in Python similar to the last python tutorial here also I will do three examples demonstrating each of the three parameters of the function which we just discussed in the last tutorial we use the command prompt for the demonstration but today our choice of editor will be Adam so let's start in order to perform a search we will need a string this is strings work as a base string onto which the string method and swig will perform the search so for today our base string will be with repent in radio.com I will be the master of Python in no time here we have the base of string next we will search if this a string or a part of it ends with a service string or not to do that we will use the ends with a string method of Python in the first example we will see if this string ends with the word time or not here I created a variable my underscore STR and saved our basis string into it next using this variable we will call the string method and sweat let's see how here I first wrote the name of the variable which is holding the paper string onto which we want to perform the search followed by that I have a dot operator and then the name of our method ends with as you can see here we have supplied only one parameter to this method which is the search string on execution the interpreter will start searching the entire string and see if it ends with the specified search string which in our case is time if the pc string ends with the search string then it will return true otherwise it will return false let's execute and see the result so the program executes without any error but where is the result unlike command-line interface where the function call directly shows the result in editor like Adam we need to take help of print function to display the result back to the user to do that we have two ways in the first one we can create another variable and store the result produced by the function call into it then using print function we can display the value is stored into that variable the second way is that we can directly place the function call into the print function that way we don't have to declare an extra variable I guess the second one will be much nicer let's go with that now if we execute the code we will see the output here we go the output is true now let's do the next example let's see I don't want the interpreter to start the search from the beginning of the string rather I want it to start the search from index number 39 that way we can save time and resources so what do I have to do for that in order to start discharge from a specific index we need to mention the index number as the second parameter of the aunts wait function call like there's simply right after the searches train put a comma and then write the index number from where you want the interpreter to start the search in my case it's 39 let's modify this function call a little bit more let's say this time I want this urge to start from index 39 and and at index 55 also instead of time let's see if the string ends with the word Python or not in this function call we have used all the three parameters let's execute and see the result the result is true so that's how we use ends with a string method in Python hope you enjoyed watching please hit
