The best way to Loop Using Python Enumerator in [2021]

Your progress

Python loop

Imagine the python loop be simple and orderable, how would you feel?

So, you’ve imagined the easy way to do looping.

But one minute what’s the way?

Ah! the way is like a 1…2…3.

The way is python enumeration.

Python enumeration is a technique to do looping in an easy way.

Thus, this blog post will give you a new aspect to looping.

As a programmer, you’ve to think differently.

And Remember, the slogan of apple in 1997 was “Think different”.

“Think different” slogan blasted Apple’s sales.

Because people want to think differently.

So, you can apply this to the python loop.

Make the looping easy as you wish.

You can use enumerate() function to what you’ve imagined. Thus you can give index numbers in the loop.

But why do you need an index number in a loop?

You need an index number to find the position of the iterable.

With enumerate, you can create an order in iterables.

Python enumeration

For example,

enumerator in list
enumerate() for list

In the above example, you can see that list has come up with a counter.

For instance, you’ve to find the position of 23. so, you can see that position of 23 is the 1st index.

This is the example of python enumerate().

Let’s discuss the syntax of it.

Syntax of python enumerator

As you know, the syntax is the rule of programming languages.

Likewise, the python enumerator has syntax.

Syntax of python enumerator is enumerate(variable, start position).

Here, the start position is optional.

If you want to start your iterable other than 0. then it’s useful.

For example,

python enumerator with start position

In the above example, you can see that list is starting with the 20th position.

Thus, you can start iterable with any index.

Enumerate() : Return value

Thus, you’ve seen the syntax of enumerating.

You can observe the python enumerate() returns the index and iterable.

So, the return value shows the counter of the iterable.

Enumerate() in for loop

Loops are very important in python.

It makes python easy and simple. You’ve done looping in the python compiler.

The compiler makes large tasks in the form of iterable.

Thus, counter or index number for iterables is important in for loop.

I’m going to show you the python enumeration in for loop.

Python enumerate() in for loop produce counter for each iterable.

For example,

enumerate() in for loop

In the above example, you can see that I’ve come up iterable with the counter.

So, here you can see that counter is starting with 0.

Also, you can see that every iterable comes in the form of a tuple.

But you only need sequence and counter.

Thus, you can add one variable in x. Hence, for loop statement becomes

for count,x in enumerate(a):

Let’s see the output of it.

For example,

enumerate() in for loop with standard output

The above example, showing you the standard output of the python enumerator.

But you want to rebel against 0. And say, ” Hey I don’t want to start my iterable with 0 “.

So, the Python enumerator will say,” Don’t worry I’ve optional parameter start. Use it”.

You say, “How to use it ?”

Here’s the trick.

You can put the start parameter inside the enumerator.

For example, you’ve to start your iterable with 100. so you’ll write

for count,x in enumerate(iterable,start = 100)

Let’s see it with the example,

enumerate() with start parameter

So, I’ve solved your problem. You can start your iterable with any position.

At last, you’ve seen the enumeration in for loop.

Why should you use python enumerator?

Finally, you would say,” Why should I use it ?”

You should use it because you want to find the counter of iterables.

For example, you’ve to come up with a players sequence. Meanwhile, you’ve to find the counter of players.

Suppose, you’ve to know what’s your position in the team. When your batting will come and rest of it.

Also, you can use python enumerate() when there is a large number of iterables.

It can be thousands of students in your college. And you want sequence with their roll no then you can use it.

Applications of python enumerator

Python enumerator() give you the freedom to the auto-increment in sequence.

Meanwhile, you can see the sequence.

That means you don’t have to write a function for increasing the counter number.

So, here’s the question. What’s the day to day example to it?

You can use the sequence of the cars.

In racing, you can find the sequence of the counter with their rank.

Also, to create a one-family ticket you can use a python enumerator.

It will create a counter and the name of each passenger.

So, what do you think?

Give me examples of the python enumerator. What’s a new example?

You’ve seen some examples of python enumerators.


Finally, you’ve come to a point where you’ve seen all things related to the enumerator.

As you saw enumerator give YOU a counter for iterable.

Thus, you can create an application for storing data with the sequence numbers.

Also, counter are used in the railway systems.

So, where you’re going to use python enumerator next?
