What is zip function in Python?
What is zip? Any person who is having some technical knowledge can quickly say that it is a tool to combine many items in a single file and can be transmitted over easily. Even a non-technical person will think of it like it is used to get things together. So in python also zip function in python will do the same thing…“combine”.

Well, then how does it work in Python. let us know
list1=[1,2,3,4]
tuple1=(‘a’,’ b’,’ c’,d’)
Now introduce the ‘zip’ method…
combined=zip(list1,tuple1)
print(combined)
We expect the output something like a combination of both list and tuple. But instead of that, it will give nothing. Why because the zip is an iterator object. We have to go through it by using for loop to view what are the elements present in the zip object.
for i in combined:
print(i)
The output will be
(1, ‘a’)
(2, ‘b’)
(3, ‘c’)
(4, ‘d’)
By looking at the output one can quickly notice what zip() is doing here. It is generating one tuple object by combining the first elements of the list and tuple together. Want to learn more about data science? Enroll in the Data Science Course in Hyderabad to do so.
Well consider the case in which, the size of both sequences which are passed into zipping () method is different then, will it work? let’s test with a code example: let’s test with a code example:
list1=[1,2,3]
tuple1=(‘a’,’ b’, ’c’, ’d’)
for i in zip(list1,tuple1):
print(i)
Now is there any error because of different length objects passed..? No, it works fine. Zip() method will go with the object with minimum length. So the output will be…
(1, ‘a’)
(2, ‘b’)
(3, ‘c’)
Is there any rule like , we have to pass only 2 sequences into the zip() method? No we can pass multiple number of objects. The only condition is the type of objects should be in sequence.
list1=[1,2,3]
tuple1=(‘a’,’b’,’c’,’d’)
set1={10,11,12,14}
dict1={‘p’:’python,’z’:’zip’}
combined= zip(list1,tuple1,set1,dict1)
for i in combined:
print(i) – the output will be as follows…
(1, ‘a’, 10, ‘p’)
(2, ‘b’, 11, ‘z’)

If a non-technical ordinary man may ask “a zip can close the bag/cloth and as well as open it. What about your zip method?”— Can it only do one task i.e. combine ?—No, our zip method in Python can do both things.
Let’s have a look at the following:
combined=zip(list1,tuple1,set1,dict1)—We have seen what it will do…
var1,var2,var3,var4=zip(*combined)
print(var1) — (1, 2)
print(var2) —(‘a’, ‘b’)
print(var3)— (10, 11)
print(var4) — (‘p’, ‘z’)
You see the output of above code snippets.

So the same zip() method is splitting the data which is combined earlier.
It combined 4 objects earlier. Now it is de-combined into 4 objects again. Observe the syntax
Where we do splitting. There should be a * mark inside the zip method.
We learned about what is zip() in python and what it can do.
