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()[0][0]
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))

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']
