🚀 Day 69/150 – Check Anagram in Python

An anagram means two strings contain the same characters in a different order.

✅ Example

listen → silent
race → care

Both words contain the same letters, so they are called anagrams.

🔹 Method 1 – Using  sorted()


str1 = "listen"

str2 = "silent"

if sorted(str1) == sorted(str2):
    print("Anagram")
else:
    print("Not Anagram")







✅ Output

Anagram

📌 sorted() arranges characters alphabetically and compares both strings.

---

🔹 Method 2 – Taking User Input

str1 = input("Enter first string: ")
str2 = input("Enter second string: ")

if sorted(str1.lower()) == sorted(str2.lower()):
    print("Anagram")
else:
    print("Not Anagram")







✅ Example Output

Enter first string: Heart
Enter second string: Earth

Anagram

📌 lower() ignores uppercase and lowercase differences.

---

🔹 Method 3 – Using Dictionary Count

str1 = "race"

str2 = "care" count1 = {} count2 = {} for ch in str1: count1[ch] = count1.get(ch, 0) + 1 for ch in str2: count2[ch] = count2.get(ch, 0) + 1 if count1 == count2: print("Anagram") else: 

print("Not Anagram")

Output

Anagram

📌 This method compares the frequency of each character.

---

🔹 Method 4 – Using Function

def is_anagram(str1, str2):
    return sorted(str1.lower()) == sorted(str2.lower())

print(is_anagram("listen", "silent"))




✅ Output

True

📌 Functions make the code reusable and cleaner.

---

🔥 Key Takeaways

✅ Anagrams contain the same characters in different order
✅ sorted() is the easiest and most popular method
✅ Dictionary counting helps understand character frequency
✅ lower() avoids case mismatch problems
✅ Anagram problems are common in coding interviews

🚀 Day 68/150 – Replace Characters in String in Python

Sometimes we need to replace characters or words inside a string.

Example:
"Python" → Replace "P" with "J" → "Jython"

Python makes this super simple using different methods 👇

🔹 Method 1 – Using  replace()

text = "Python"

result = text.replace("P", "J")

print(result)




✅ Output

Jython

📌 replace() replaces all matching characters or words in a string.

---

🔹 Method 2 – Taking User Input

text = input("Enter a string: ")

old_char = input("Enter character to replace: ")
new_char = input("Enter new character: ")

result = text.replace(old_char, new_char)

print("Updated String:", result)








✅ Example Output

Enter a string: banana
Enter character to replace: a
Enter new character: o

Updated String: bonono

📌 Useful when replacement values come from the user.

---

🔹 Method 3 – Using for Loop

text = "apple"

result = ""

for ch in text:
    if ch == "p":
        result += "b"
    else:
        result += ch

print(result)










✅ Output

abble

📌 This method manually checks every character and replaces matching ones.

---

🔹 Method 4 – Using List Comprehension

text = "hello"

result = "".join(["*" if ch == "l" else ch for ch in text])

print(result)





✅ Output

he**o

📌 A compact and Pythonic way to replace characters.

---

🔥 Key Takeaways

✅ replace() is the simplest method
✅ Loops help understand string manipulation logic
✅ List comprehension makes code shorter and cleaner
✅ String replacement is useful in text processing and cleaning
✅ Strings are immutable, so replacement creates a new string

🚀 Day 67/150 – Remove Spaces from String in Python

Sometimes while working with strings, we need to remove spaces from text data.

Example:
"Python Programming" → "PythonProgramming"

Python provides multiple easy ways to do this. Let’s explore them 👇

🔹 Method 1 – Using replace()

text = "Python Programming"

result = text.replace(" ", "")

print(result)





✅ Output

PythonProgramming

📌 replace() replaces all spaces with an empty string.

---

🔹 Method 2 – Taking User Input

text = input("Enter a string: ")

result = text.replace(" ", "")

print("After Removing Spaces:", result)

✅ Example Output

Enter a string: Python Programming
After Removing Spaces: PythonProgramming

📌 Useful when working with user-entered text.

---

🔹 Method 3 – Using split() and join()

text = "Python Programming"

result = "".join(text.split())

print(result)





✅ Output

PythonProgramming

📌 split() separates words and join() combines them without spaces.

---

🔹 Method 4 – Using for Loop

text = "Python Programming" result = "" for ch in text: if ch != " ": result += ch print(result)

✅ Output

PythonProgramming

📌 This method manually checks each character and skips spaces.

---

🔥 Key Takeaways

✅ replace() is the easiest method
✅ split() + join() is clean and efficient
✅ Loops help understand string manipulation logic
✅ Removing spaces is useful in text cleaning tasks

🚀 Day 64/150 – Count Vowels in a String in Python

Vowels are the letters: a, e, i, o, u.
In Python, we can count vowels in a string using loops, list comprehensions, and functions.

Let’s explore different ways to count vowels in Python 👇

🔹 Method 1 – Using for Loop

text = "Python Programming"

count = 0

for ch in text.lower():
    if ch in "aeiou":
        count += 1

print("Vowel Count:", count)








✅ Output

Vowel Count: 4

📌 Loops through each character and increases the count when a vowel is found.

🔹 Method 2 – Taking User Input

text = input("Enter a string: ")

count = 0

for ch in text.lower():
    if ch in "aeiou":
        count += 1

print("Vowel Count:", count)








📌 Allows the user to enter any string dynamically.

🔹 Method 3 – Using List Comprehension
text = "Python Programming"

count = sum([1 for ch in text.lower() if ch in "aeiou"])

print("Vowel Count:", count)



✅ Output
Vowel Count: 4
📌 Short and Pythonic way to count vowels.
🔹 Method 4 – Using Function
def count_vowels(text):
    count = 0

    for ch in text.lower():
        if ch in "aeiou":
            count += 1

    return count

print(count_vowels("Python Programming"))







✅ Output
4
📌 Best approach when you want reusable code.

🔥 Key Takeaways
✅ lower() helps handle uppercase and lowercase letters

✅ in "aeiou" is an easy way to check vowels

✅ List comprehensions make code shorter

✅ Functions improve reusability and readability
