print(Word[:4])

"Revi"

.right(number of characters)

Word = "Revision"

print(Word.right(4))

Word = "Revision"

print(Word[4:])

"sion"

FullName = FName + SName

print(FullName)

FName = "Sarah"

SName = "Jones"

FullName = FName + SName

print(FullName)

"SarahJones"

FName = "Sarah"

SName = "Jones"

FullName = FName + " " + SName

print(FullName)

FName = "Sarah"

SName = "Jones"

FullName = FName + " " + SName

print(FullName)

"Sarah Jones"

Name = "Sarah"

print("Hello, " + Name)

Name = "Sarah"

print("Hello, " + Name)
