# Useful One-Liners In Python – A Quick Guide Python is one of the most powerful and user-friendly programming languages ever created. Python is popular among programmers because it simplifies complicated tasks.

This tutorial will go through some easy and entertaining one-liners. Let’s get started!

## Combine the contents of two dictionaries into a single one.

If you’re using Python3.9 or above, you may use | for this.

```x = {'a': 11, 'b': 22}
y = {'c': 13, 'd': 44}
z = x | y
print(z)
```

The output looks like this:

```{'a': 11, 'b': 22, 'c': 13, 'd': 44}
```

## Get the most frequent element

Let’s utilize the `most_common()` function from the collections module to achieve this.

```from collections import Counter
l = ['1', 'b', '2', 'a', '3', 'z', '3', 'a', '2', '3']
Counter(l).most_common()
```

The code returns ‘3’ as the output which is correct!

## Get quotient and remainder at the same time

`divmod()` returns a tuple and its functionality stems from the fact that it combines modulo percent and division/operators.

```Q, R = divmod(35632, 5)
print("Quo. - ",Q)
print("Rem. - ",R)
```
```Quo. -  7126
Rem. -  2
```

## Find the first n Fibonacci numbers

This will be an excellent exercise on remembering lambda functions and recursion in Python.

```fib = lambda x: x if x <= 1 else fib(x - 1) + fib(x - 2)
print(fib(20))
print(fib(5))
```
```6765
5
```

## Remove duplicate elements from a list

```list(set(['1', '1', '2', '1', '3']))
```

In Python, each element in a set is unique, therefore there will be no duplicates.

```['1', '3', '2']
```
