Master Python strings with this guide. Learn string manipulations, methods, slicing with examples to improve your Python coding skills fast.

What is a String?

A string is a sequence of characters enclosed in quotes.
- Examples: "hello", 'Python', "1234"

name = "Alice"
greeting = 'Hello'

Concatenation (joining strings):

first = "Hello"
second = "World"
result = first + " " + second  # Output: "Hello World"

Repetition:

word = "Hi"
print(word * 3)  # Output: "HiHiHi"

Indexing:

text = "Python"
print(text[0])  # Output: "P"
print(text[-1]) # Output: "n"

Slicing:

text = "Python"
print(text[0:3])  # Output: "Pyt"
print(text[2:])   # Output: "thon"

Instruction:
Take two words like "Hello" and "World" and combine them into one sentence with a space in between.

Concept: String concatenation using the + operator.

Instruction:
Given the word "Python", find out what the first character and the last character are.

Concept: Accessing characters using index numbers (positive and negative indexing).

Instruction:
From the word "Python", extract only the first three letters.

Concept: String slicing (extracting parts of a string using index ranges).

Instruction:
Enter any word or sentence and find out how many characters it contains.

Concept: Using the len() function to count characters.
