As you are now already familiar with the input<\/strong> function which is used for data input. Also, you must be familiar now that the input<\/strong> function returns data as String<\/strong> type. Scenarios where you want your users to input the value as a number (int<\/strong> or float<\/strong> type). Python provides functions to typecast String types to numbers and numbers to String types.<\/p>\n\n\n\n

Type Casting<\/strong>\u00a0(or type conversion) allows you to change the data type of a variable<\/strong>.<\/p>\n\n\n\n

operand = int (input ('Enter the Number: '))\noperand = float (input ('Enter Number in fractional value'))\nprint('You entered the value = + str(operand))<\/strong><\/code><\/pre>\n\n\n\n
There are two main types of type casting: <\/p>\n\n\n\n
    \n
  1. Implicit Type Casting<\/strong>:   In this method, Python automatically converts one data type into another without user intervention.<\/li>\n\n\n\n
  2. Explicit Type Casting<\/strong>:    In this method, you explicitly convert a variable to a specific data type using predefined functions.<\/li>\n<\/ol>\n<\/div>\n\n\n\n

    Examples<\/h2>\n\n\n\n
    \n
    Implicit Type Casting<\/h3>\n\n\n\n
    Python implicitly converts\u00a0a<\/code>\u00a0(an integer) to a float<\/strong> for addition and multiplication.<\/p>\n\n\n\n
    a = 7\nb = 3.0\nc = a + b<\/strong>     # Result: 10.0 (float)<\/em>\nd = a * b<\/strong>     # Result: 21.0 (float)<\/em><\/code><\/pre>\n\n\n\n
    <\/div>\n<\/div>\n\n\n\n
    \n
    Explicit Type Casting<\/h3>\n\n\n\n
    \n
    Convert\u00a0int<\/code>\u00a0to\u00a0float<\/code><\/p>\n\n\n\n
    a = 5\nn = float(a)<\/strong>     # Result: 5.0 (float)<\/em><\/code><\/pre>\n\n\n\n
    \n<\/div>\n\n\n\n
    \n
    Convert\u00a0float<\/code>\u00a0to\u00a0int<\/code><\/p>\n\n\n\n
    a = 5.9\nn = int(a)<\/strong>  # Result: 5 (integer)<\/em><\/code><\/pre>\n\n\n\n
    \n<\/div>\n\n\n\n
    \n
    Convert\u00a0int<\/code>\u00a0to\u00a0str<\/code><\/p>\n\n\n\n
    a = 5\nn = str(a)<\/strong>  # Result: '5' (string)<\/em><\/code><\/pre>\n\n\n\n
    \n<\/div>\n\n\n\n
    \n
    Convert\u00a0str<\/code>\u00a0to\u00a0float<\/code>:<\/p>\n\n\n\n
    a = \"5.9\"\nn = float(a)<\/strong>  # Result: 5.9 (float)<\/em><\/code><\/pre>\n\n\n\n
    \n<\/div>\n\n\n\n
    \n
    Convert\u00a0str<\/code>\u00a0to\u00a0int<\/code>\u00a0(with error handling)<\/p>\n\n\n\n
    a = \"5\"\ntry:\n    n = int(a)<\/strong>  # Result: 5 (integer)<\/em>\nexcept ValueError:\n    print(\"Invalid input\")<\/strong><\/code><\/pre>\n\n\n\n
