Type conversion functions are used in programming to convert data to primitive datatypes.
Type Conversion in Python
- str(x) returns a string version of x. Almost all datatypes support this function, and you can use it on your own classes by implementing the __str__ function.
- int(x) converts x into an integer. Floats will be rounded down to the nearest integer, and strings that don't represent a valid integer will result in an error.
- float(x) converts x into a floating point number. Strings that don't represent a valid floating point number will result in an error.
- list(x) converts any iterable x into a list.
