Looking Inside the Strings

We can use indexing to get a specific character from a string or if we need to get a range of characters, then we use slices. It is important to note that the value of the index must be an integer. In Python, indexing starts from 0. If we try to access the string item outside the range then we will get an error Index Error. In Python there is also the possibility of negative indexing, in this case -1 is the index of the last element, -2 is the penultimate one, and so on.

# Accessing string characters
string = 'Hello, World'
print('string = ', string)

# Accessing the first character
print(f'The first character is "{string[0]}"')

# Accessing the last character
print(f'The last character is "{string[-1]}"')

Ending index is up to but not including.

Indexing starts from 0.

Task

Swipe to start coding

You have such string watermelon. You have to get such characters: n, m, l, a. Use only positive indexing.

Solution

string = 'watermelon'
n = string[9]
m = string[5]
l = string[7]
a = string[1]
print(n, m, l, a)

Everything was clear?

How can we improve it?

Thanks for your feedback!

Section 3. Chapter 3
string = 'watermelon'
n = string[_ _ _]
m = string[_ _ _]
l = string[_ _ _]
a = string[_ _ _]
print(n, m, l, a)
