Creating Strings

You can create a string by enclosing characters in single (' ') or double (" ") quotes. Triple quotes (''' ''' or """ """) are used for multiline strings.

Here are 10 coding examples for string-related tasks in Python:

String Concatenation:

str1 = "Hello"
str2 = "World"
result = str1 + " " + str2
print(result)  # Output: Hello World

String Length:

string = "Python is awesome"
length = len(string)
print(length)  # Output: 18

String Splitting:

sentence = "This is a sample sentence."
words = sentence.split()
print(words)  # Output: ['This', 'is', 'a', 'sample', 'sentence.']

String Joining:

words = ['Hello', 'World']
sentence = ' '.join(words)
print(sentence)  # Output: Hello World

String Case Conversion:

text = "Python Programming"
lower_text = text.lower()
upper_text = text.upper()
print(lower_text)  # Output: python programming
print(upper_text)  # Output: PYTHON PROGRAMMING

String Replacement:

sentence = "I like apples."
new_sentence = sentence.replace('apples', 'bananas')
print(new_sentence)  # Output: I like bananas.

String Searching:

text = "Python is powerful"
if 'powerful' in text:
    print("Found")
else:
    print("Not found")

String Formatting:

name = "Alice"
age = 30
formatted_string = f"My name is {name} and I am {age} years old."
print(formatted_string)

Removing Whitespace:

text = "   Some spaces here   "
stripped_text = text.strip()
print(stripped_text)  # Output: "Some spaces here"

Substring Extraction:

string = "Hello, World!"
substring = string[7:12]
print(substring)  # Output: World
