Length of a String

We can find the length of a string using len() function.

Example:

fruit = "Mango"

len1 = len(fruit)

print("Mango is a", len1, "letter word.")

Output:

Mango is a 5 letter word.

String as an array

A string is essentially a sequence of characters also called an array. Thus we can access the elements of this array.

Example:

pie = "ApplePie" print(pie[:5])

print(pie[6]) #returns character at specified index

Output:

Apple

i

Note: This method of specifying the start and end index to specify a part of a string is called slicing.

Slicing Example:

pie = "ApplePie"

print(pie[:5]) #Slicing from Start

print(pie[5:]) #Slicing till End

print(pie[2:6]) #Slicing in between

print(pie[-8:]) #Slicing using negative index

Output:

Apple

Pie

pleP

ApplePie

Loop through a String:

Strings are arrays and arrays are iterable. Thus we can loop through strings.

Example:

alphabets = "ABCDE"

for i in alphabets:

print(i)

Output:

A

B

C

D

E
