Python Datatype Conversion

1. Datatypes Conversion

Datatypes conversion means the conversion of the datatype from one type to another type. For example, if you are converting string datatype to integer datatype that's a datatype conversion.

Python has two types of type conversion:

1. Implicit Type Conversion

   In this type of data conversion in python, python directly converts one data type to another data type. Data conversion is done automatically with the help of Implicit Type Conversion. Python converts the data from lower types to higher data types in order to prevent data loss. Data conversion is done automatically by the python interpreter.

   Example:

           
   >>>a=2
   >>>b=3.2
   >>>c=a+b #data is converted implicitly from integer to float.
   >>>print(c)
      5.2
   >>>#Another example
   >>>a=2
   >>>b=2+3j
   >>>c=a+b
   >>>print(type(c))
      <class 'complex'>
           
       

2. Explicit Type Conversion/Casting

   Explicit Type Conversion means conversion of datatypes with the involvement of the user. We can convert data to the required type with the help of some functions like int(), float(), str(), complex(), etc.
   Conversion syntax: cast-type(data).

   Example:

   
   >>>a='12'
   >>>print(type(a))
      <class 'str'>
   
   >>>b=int(a) #cast to int
   >>>print(type(b))
      <class 'int'>
   
   >>>c=float(a) #cast to float
   >>>print(type(c))
      <class 'float'>
   
   >>>d=complex(a) #cast to complex
   >>>print(type(d))
      <class 'complex'>
           

   Note:

   Explicit type conversion is also called as type-casting in python.

   Type Casting functions and conversions

   SN	Functions	Conversions
   1	int()	string, float to int.
   2	float()	string, int to float.
   3	str()	int,float,list,tuple,di-ctionary to string.
   4	complex()	int,float to complex.
   5	set()	string, list, tuple to set.
   6	list()	string,tuple,set,dictionary to list.
   7	tuple()	string,list,set to tuple.
