# Sử dụng toán tử + để ghép chuỗi
s = "Hello" + " " + "world"
print(s)  # Hello world
 
# Sử dụng toán tử * để lặp chuỗi
s = "Hello" * 3
print(s)  # HelloHelloHello
 
# Sử dụng template string
s = "Hello %s" % "world"
print(s)  # Hello world
 
# Sử dụng f-string
t = "world"
s = f"Hello {t}"
print(s)  # Hello world
 
s = f"Hello {'world'}"
print(s)  # Hello world
 
# Ghép chuỗi bằng hàm join
s = ["Hello", "world", "I", "love", "Python"]
print(" ".join(s))  # Hello world I love Python
print(".".join(s))  # Hello.world.I.love.Python
print("".join(s))  # HelloworldIlovePython
 
t = " "
print(t.join(s))  # Hello world I love Python
print(t) # " " - Không làm thay đổi chuỗi gốc
