Thus, you might have learned how you can download a zip file from a URL in Python using the requests module.

You can verify the download in the location of your Python source code file. To unzip a sequence we have to use the zip() function with the unpacking operator *.Downloading a zip file using the requests module The zip() function can perform both zipping and unzipping of sequences. The answer to this question is the zip() function itself. But now the question that comes in mind is ‘How can we unzip a sequence?’ Is there any inbuilt method that does just the reverse of the zip()? Well, there is no such inbuilt method in Python. Till now, we have understood a lot about zipping the sequences. Print(k2,': ', v2) Output: first_name : John We have zipped these two lists and created a single dictionary from them. In the below example, we have two lists containing information of a student. This can be easily achieved using the zip() function. Sometimes, you might have a requirement where you need to build a dictionary from two similar types of sequences.
The remaining items(‘d’, ‘e’ & ‘f’) have no match therefore they are completely ignored. Therefore only the first three items from both the iterables are considered. In the above example, the length of the shortest iterable is 3. The remaining items in the longer iterables are completely ignored by the zip() function. In such cases, the zip() function returns an iterator which has the same length as the shortest iterable. There might be situations where the length of the iterables that we are passing as the arguments is unequal. In this case, the zip() function returns an empty iterator. You can also call the zip() function without passing any arguments to it. In this case, the zip() function returns an iterator that contains a list of 1-item tuples. The zip() function can also take just one argument.
Students = zip(first_name, last_name, age) age to the zip() function and our task will be done. To do that we have to pass one more parameter i.e. Now, let’s add one more field, the age of the students with their corresponding first and last names. In the previous example, we zipped the first names with their corresponding last names using the zip(). Print(list(students)) Output: Įxample 2: Combining first name, last name and age See the example below: Example 1: Combining first name and last name first_name = The Python zip() function aggregates elements that are on the same index in different iterables and returns an iterator containing all such combinations. How would you do that? Well, the answer is the Python zip() function. Your task is to combine the first names with the corresponding last names. Suppose, you have two lists containing the first names and last names of university students. Now, let’s understand it with the help of a real-world example. This zip object can later be converted to any type of iterable such as list, dictionary, set, etc.Īt the beginning of this tutorial, we learned that the Python zip() function aggregates elements from two or more iterables and results into a single iterator. This zip object is basically an iterator containing items from all the iterables passed to the zip() function. It can take any number of iterables at a time. The zip() function takes in iterables as arguments such as lists, sets, tuples, dictionaries, etc. The syntax of the zip() function is as follows: zip(*iterables) This iterator can later be converted to any desired type of iterable like a list, dictionary, etc based on the requirement. The result of the zip() function is an iterator of tuples that contains elements from each iterable you have passed into the zip(). The Python zip() function aggregates elements from two or more iterables and zip them into a single iterable.
