String Operations

What is a String ?

A string is a sequence of characters (letters, numbers, symbols, spaces, etc.) enclosed within quotes.

In simple words:
Text data = String

How to create a string

You can use:

• Single quotes ' '
• Double quotes " "
• Triple quotes ''' ''' or """ """ (for multi-line)

name = "Silambu"
city = 'Chennai'
msg = """This is
multiple line string"""

• String is immutable → you cannot change characters directly
• Each character has an index (position)

text = "Python"

print(text[0])  # P
print(text[1])  # y

Common string operations

name = "silambu"

print(name.upper())      # SILAMBU
print(name.capitalize()) # Silambu
print(name.lower())      # silambu
print(len(name))         # 7
print("My name is " + name) #My name is Silambu

Both first & last letter capital

name = "silambu"

result = name[0].upper() + name[1:-1] + name[-1].upper()

print(result)

Output: SilambU

• First letter → name[0].upper()
• Last letter → name[-1].upper()
