![]() the separator is still a string, but it's a string with simply a single space. So the correct way of joining the first and last names is to first create a sequence of the words, and then join it with a space separator i.e. And since only one string was provided in the parameters of the join() function, every element / character of the string "Bunny" was separated with the word "Bugs" in the middle. So, the join function considered the first string, i.e. In the example above, when we wrote first_name.join(last_name) it was the same as Bugs.join("Bunny"). The join function will join the two(or more) strings but will leave the separator character between each of the strings. As in, the syntax requires a string, and that string is a supposed to be a separator. ![]() Wait, what? That's not what we expected! Well, the join() function joins a separator to a sequence of words. To create an empty list in python, here's the syntax you can follow: They are used to store multiple data at the same time. Python lists are mutable, which means that even after they have been created, they can be altered. They could be strings, integers, float, objects or even other lists or a mix of all these as shown in the examples below. Lists can contain variables of different data types and even of same data types. Lists in Python are the same as the definition of arrays above, except, python lists, unlike arrays, need not be homogenous (homogenous means of same data type). They are collections of a data type stored in contiguous parts of memory, as in continuous memory. You must have heard of the term arrays, in other programming languages like C, Java, C++. However, you can use string methods such as replace() if you wish to update the string. What was the output that you got? You got a type error. Any set of characters enclosed in single or double quotes denote a string. What is a String in Python?Ī string by definition is an immutable data type which can't be changed once declared in a program (explained below). Either way, it would be convenient for you to convert your list into a string.īefore we go deep into discussing the numerous ways that we could do so, let's learn about lists and strings first. And now you want the URL to of course, be a string, you would have to join all the elements of the list to make it a string. Or maybe like in the scenario above you have some components of a URL fetched, but in the form of a list. ![]() You might want to display the contents of the list, or you might want to perform string manipulations on elements of the list. It is very common in python, that you would want to convert lists to strings or vice versa. ![]() But now how will you convert it back to the string format it was in earlier?! You figured out how to break the URL into a list, or maybe while you were working with the URLs, you received the input as a list. Now you can freely modify the complete URL anyway you want. What's easier, is to break it into it's sections and then put them in a list. You know for a fact that the URL is a string, how will you access the exact elements you want to change? Keeping track of it's indices, or the words would be so cumbersome! Now suppose you want to make some very minor changes to that URL. Have you worked with URLs? The ones you see on the top of your browser (links, as one might call them)? They are made of different sections, like the scheme, the domain etc. To convert a list to string in Python Programming, you can make use of the join() function, but with a separator, or by traversing the list, the map() function, or with one of the fastest operations in Python - list comprehension. ![]()
