Python Coding challenge - Day 194 | What is the output of the following Python Code?

 

Code: 

s = 'clcoding'

print(s[-6:-1:2])

Solution and Explanation:

Let's break down the code s = 'clcoding' and print(s[-6:-1:2]) step by step:

s = 'clcoding': This line of code assigns the string 'clcoding' to the variable s.

s[-6:-1:2]: This is called string slicing. Let's break it down:

s[-6:-1]: This specifies a substring of s starting from the 6th character from the end (counting from the right) and ending at the 1st character from the end. Negative indices in Python count from the end of the string.So, in 'clcoding', the characters at these positions are:

-6: 'c'

-5: 'l'

-4: 'c'

-3: 'o'

-2: 'd'

The substring extracted by s[-6:-1] is 'clcod'.

s[-6:-1:2]: This specifies that we want to take every second character from the substring 'clcod'.So, starting from the first character 'c', we take every second character:

'c': 0th position

'c': 2nd position

'd': 4th position

Thus, the final result printed would be 'ccd'.

So, print(s[-6:-1:2]) would output 'ccd'.
