It is used to map the similar index of multiple containers so that they can be used just using a single entity. The idea is about merging iterables, which comes handy in many cases. Python zip () method takes iterable or containers and returns a single iterator object, having mapped values from all the containers. Working with zip function in Python is pretty neat and easy. We can convert the zip object to a tuple then to a string and write the string to the file: f.write(str(tuple(zip(list_1,list_2))))

PYTHON IZIP EXAMPLE CODE

The following will be the contents of the file:Īlso, there is a shorter code instead of using the for loop. Now close the file and check the saved data. List_2 = įinally, use the for loop to iterate through lists in zip function and write the result in the file (after converting a tuple to string): for i in zip(list_1, list_2): Now let’s create two lists to zip together. If the file doesn’t exist, it will be created. Use the following line: f = open('zipOutput.txt', 'a+')

The first step is to open a file (we will use the append mode so nothing of existing content will be deleted). To save the output from the zip function into a file. That’s why we said before the length of the output equals the length of the smallest iterator, which is 2 in this case. By voting up you can indicate which examples are most useful and appropriate. Similarly, the second elements of all of them are joined together.īut there is no third element in the iterator y therefore, the third elements of remaining iterators are not included in the output object. Here are the examples of the python api taken from open source projects. The first elements of all of them are joined together. In the above example, we defined three iterators of different lengths. are the iterator objects that we need to join using the zip function.Ĭonsider the following snippet, where we have three iterables and the zip function joins them together. In the syntax above, the iterable0, iterable1, etc. Iterables can be Python lists, dictionary, strings, or any iterable object. Syntax: zip(iterable0, iterable1, interable2, …) If the iterables in the zip function are not the same length, then the smallest length iterable decides the length of the generated output. Now write the following code for reading zip file. read command is used for reading zip files. Reading Zip Files Now to read zip files, you have to open your file in reading (r) mode.

The zip function pairs the first elements of each iterator together, then pairs the second elements together and so on. Python Zip File Example You can see two text files has been written into zip file.
