Working with Strings 🧵
Text values are called strings. Python gives you a huge toolkit for slicing, joining and transforming them.
f-strings: the best way to build text
name = "Grace"
print(f"Hello {name}, you have {3 * 4} messages")Useful methods
s = " Python Rocks "
print(s.strip()) # remove spaces at both ends
print(s.lower()) # " python rocks "
print(s.upper())
print("a,b,c".split(",")) # ['a', 'b', 'c']
print("-".join(["x","y"])) # x-y
print("hello".replace("l","L"))
print(len("hello")) # 5Indexing and slicing
word = "Pythonaut"
print(word[0]) # P
print(word[-1]) # t
print(word[0:6]) # Python
print(word[6:]) # aut
print(word[::-1]) # reversed💡 Strings are immutable. Methods return a new string; the original never changes.
Your challenge
Given word = "racecar", print the word reversed, then print True if it is a palindrome (same backwards) using a comparison, then print the word in capitals.
