1. Looping through a List
#Common Approach:
numbers = [1, 2, 3, 4, 5]
for num in numbers:
print(num)
# Output: 1 2 3 4 5
#Simple Approach: numbers = [1, 2, 3, 4, 5] print(*numbers) # Output: 1 2 3 4 5
2. Reversing a String
#Common Approach:
text = "hello"
reversed_text = ""
for char in text:
reversed_text = char + reversed_text
print(reversed_text)
# Output: olleh
#Simple Approach: text = "hello" reversed_text = text[::-1] print(reversed_text) # Output: olleh
3. Removing Duplicates from a List
#Common Approach:
numbers = [1, 2, 2, 3, 4, 4, 5]
unique_numbers = []
for num in numbers:
if num not in unique_numbers:
unique_numbers.append(num)
print(unique_numbers)
# Output: [1, 2, 3, 4, 5]
#Simple Approach: numbers = [1, 2, 2, 3, 4, 4, 5] unique_numbers = list(set(numbers)) print(unique_numbers) # Output: [1, 2, 3, 4, 5]
4. Finding Common Elements in Lists
#Common Approach:
list1 = [1, 2, 3, 4, 5]
list2 = [3, 4, 5, 6, 7]
common_elements = []
for item in list1:
if item in list2:
common_elements.append(item)
print(common_elements)
# Output: [3, 4, 5]
#Simple Approach: list1 = [1, 2, 3, 4, 5] list2 = [3, 4, 5, 6, 7] common_elements = list(set(list1) & set(list2)) print(common_elements) # Output: [3, 4, 5]
5. Finding Unique Elements in Lists
#Common Approach:
list1 = [1, 2, 3, 4, 5]
list2 = [3, 4, 5, 6, 7]
unique_elements = []
for item in list1:
if item not in list2:
unique_elements.append(item)
for item in list2:
if item not in list1:
unique_elements.append(item)
print(unique_elements)
# Output: [1, 2, 6, 7]
#Simple Approach: list1 = [1, 2, 3, 4, 5] list2 = [3, 4, 5, 6, 7] unique_elements = list(set(list1) ^ set(list2)) print(unique_elements) # Output: [1, 2, 6, 7]
6. Checking for Palindromes
#Common Approach:
text = "racecar"
is_palindrome = True
for i in range(len(text) // 2):
if text[i] != text[len(text) - 1 - i]:
is_palindrome = False
break
print(is_palindrome)
# Output: True
#Simple Approach: text = "racecar" is_palindrome = text == text[::-1] print(is_palindrome) # Output: True
7. Reversing Words in a Sentence
#Common Approach:
sentence = "Python is amazing"
words = sentence.split()
reversed_sentence = ""
for word in words[::-1]:
reversed_sentence += word + " "
print(reversed_sentence.strip())
# Output: amazing is Python
#Simple Approach: sentence = "Python is amazing" reversed_sentence = " ".join(sentence.split()[::-1]) print(reversed_sentence) # Output: amazing is Python
8. Finding the Longest Word in a Sentence
#Common Approach:
sentence = "Python programming is fun"
words = sentence.split()
longest_word = ""
for word in words:
if len(word) > len(longest_word):
longest_word = word
print(longest_word)
# Output: programming
#Simple Approach: sentence = "Python programming is fun" longest_word = max(sentence.split(), key=len) print(longest_word) # Output: programming
9. Rotating a List by K Positions
#Common Approach:
numbers = [1, 2, 3, 4, 5]
k = 2
rotated = []
for i in range(len(numbers)):
rotated.append(numbers[(i + k) % len(numbers)])
print(rotated)
# Output: [4, 5, 1, 2, 3]
#Simple Approach: numbers = [1, 2, 3, 4, 5] k = 2 rotated = numbers[-k:] + numbers[:-k] print(rotated) # Output: [4, 5, 1, 2, 3]
10. Swapping Case of Characters in a String
#Common Approach:
text = "Hello World"
swapped_text = ""
for char in text:
if char.islower():
swapped_text += char.upper()
else:
swapped_text += char.lower()
print(swapped_text)
# Output: hELLO wORLD
#Simple Approach: text = "Hello World" swapped_text = text.swapcase() print(swapped_text) # Output: hELLO wORLD
