# Climbing Stairs using Python

Climbing Stairs is one of the popular coding interview questions. It is asked in the coding interviews by FAANG companies many times. In the climbing stairs problem, you need to count the number of distinct ways to climb to the top of a staircase. So, if you want to know how to solve the climbing stairs problem, this article is for you. In this article, I will take you through how to solve the problem of climbing stairs using Python.

## Climbing Stairs using Python

In the climbing stairs problem, we need to count all the possible combinations to reach the top of a staircase. As it has a constraint, we can only climb one step or two steps at a time, so we have a choice of stepping on or skipping a step.

There are many ways to solve this problem. One of the simplest ways is to use the Fibonacci series method. So below is how you can solve the climbing stairs problem using the Python programming language:

```def climbStairs(num):
a = 1
b = 1
n = num - 1
for i in range(n):
c = a
a = a + b
b = c
return a

print(climbStairs(4))```
`Output: 5`

So this is how you can solve the climbing staircase problem using Python. You can find many more practice questions to improve your problem-solving skills using Python here.
