Question 2

How would you change the type of a variable?

Answer 2

• You can Casting to change the type of a variable.
• Casting in python is therefore done using constructor functions:
• 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
