# These methods let you search inside strings, split them, and join them back together

message = "Hello Bull"

# in — is something inside the string? Returns True or False
print("Bull" in message)   # True
print("Horn" in message)   # False

# in is case sensitive

# find() — where is it? Returns the index of the first match

print(message.find("Horn"))   # -1 — not found, no error

# count() — how many times does it appear?

# startswith() — does the string start with this?
print(message.startswith("Hello"))  # True
print(message.startswith("Bull"))   # False

# endswith() — does the string end with this?
print(message.endswith("Bull"))     # True
print(message.endswith("Hello"))    # False

# split() — break it into pieces, returns a list
