Integers and floats are data types that deal with numbers. To convert an integer to a float, use the float() function in Python. Similarly, if you want to convert a float to an integer, you can use the int() function. a_int = 3 b_int = 2 # Explicit type conversion from int to...
Implicit and Explicit Data Type Conversion Data type conversion in Python can take place in two ways, either you force Python to convert it to a specific datatype or Python itself does that during compilation. When you force the compiler for conversion, it is called Explicit Data Type Conversio...
In Implicit type conversion, Python automatically converts one data type to another data type. This process doesn't need any user involvement. Let's see an example where Python promotes conversion of lower datatype (integer) to higher data type (float) to avoid data loss. Example 1: Convert...
