​String Concatenation

• ​The + operator does not just add two numbers

• It can also “add” two strings

• The process of combining two strings is called string concatenation

• Performing string concatenation creates a brand new string comprised of the first string’s contents followed by the second string’s contents

Casting

There may be times when you want to specify a type on to a variable. This can be done with casting.

• int() - constructs an integer number from an integer literal, a float literal (by removing all decimals), or a string literal (providing the string represents a whole number)

• float() - constructs a float number from an integer literal, a float literal or a string literal (providing the string represents a float or an integer)

• str() - constructs a string from a wide variety of data types, including strings, integer literals and float literals
