Operations on Strings in Python

Length of a String

You can determine how many characters are in a string using the len() function.

Example:

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

Output:

Mango is a 5 letter word.

A string is a sequence of characters, similar to an array. This allows us to access specific characters within the string.

Example:

Copy code
pie = "ApplePie"
print(pie[:5])     # Slicing from Start
print(pie[6])      # Returns character at specified index

Output:

Apple
i

Note: The method of using start and end indices to specify parts of a string is known as slicing.

Strings are iterable, meaning you can loop through each character in the string.

Example:

alphabets = "ABCDE"
for i in alphabets:
    print(i)

Output:

A
B
C
D
E

You can combine two strings using the + operator.

Example: Merging two city names from Nepal into one string:

city1 = "Kathmandu"
city2 = "Pokhara"
combined_city = city1 + city2
print(combined_city)

Output:

KathmanduPokhara

Example with Space: To add a space between the city names:

city1 = "Kathmandu"
city2 = "Pokhara"
combined_city = city1 + " " + city2
print(combined_city)

Output:

Kathmandu Pokhara
