Type conversion
PYTHON CERTIFICATION TRAINING www.edureka.co/python Type Conversion x = (20) y = (“number is”) z = 20 Print( str(x * z) , y ) Type conversion specifies a type to a variable.
PYTHON CERTIFICATION TRAINING www.edureka.co/python Type Conversion 1. int() – This function changes any data type to integer data type. 2. float() – This function changes any data type to float data type. 3. tuple() – This function changes any data type to tuple. 4. list() – This function changes any data type to a List. 5. set() – This function changes any data type to a Set. 6. dict() – This function changes any data type to a dictionary.
