data type conversion

• Type conversion is the process of converting the value of one data type to another.
• Type conversion is of two types in Python: implicit conversion and explicit conversion.
• Implicit conversion is a type of conversion in which Python does the conversion without the involvement of the programmer which usually done to avoid loss of data.
• Python always converts smaller data types to larger data types to avoid data loss.
• Explicit conversion is a type of conversion of one data type to another that is done by the programmer.
• The syntax for conversion is given as follows:

  <required_dataType>([value])
• Python does not allow adding an integer number with a string.
• If the numbers stored in the integer and the string variables are to be added up, an explicit type conversion hasto be used.
• A statement is an instruction that the Python interpreter executes.
• instructions are the orders or commands that the computer follows to do something.
• Assignment and print() statements are the two types of statements
• An assignment statement assigns value to a variable while a print() statement displays the value that is given to it.
• it is only the print statement that produces an output.
• Expressions are what the Python interpreter evaluates to produce some value.
• An expression could be a simple literal value, a variable, or something more complex which is a combination of literals, variables, and operators
• expressions in the above table are those encircled withred.
