Type Conversion in Python

In this tutorial, you will learn about type conversion in python and its use cases with examples.

Type Conversion in Python

Type conversion is the process of converting data one form of data type to another. It is important in performing critical operations. For example, if you are comparing a string to an integer, the integer should be converted into a string first. In this way, the process is more efficient and highly accurate.

Note: You can use the type() function to identify the type of data type used in the statements

Python supports two types of Type Conversions:

1. Implicit Type Conversion
2. Explicit Type Conversion

Implicit Type Conversion

The Python interpreter automatically converts one data type to another in implicit type conversion, which means there is no user involvement in implicit type conversion.  This type of conversion is commonly used between data types like int and float.

Example

Input:

[gamipress_button type=”submit”  label=”Run Code Snippet” onclick=”window.open(‘https://coderseditor.com/?id=1201′,’_blank’)”]

a= int(input("Enter the value of a:"))

b=float(input("Enter the value of b:"))

print(type (a))

print(type(b))

c=(a+b)

print("Value of c by implicit conversion:", c)

print (type (c))

Out1put:

Enter the value of a:23
Enter the value of b:32.89
<class 'int'>
<class 'float'>
Value of c by implicit conversion: 55.89
<class 'float'>

Explicit Type Conversion

Here, the given data type is changed by the user based upon the requirement of the problem.

Example:

[gamipress_button type=”submit”  label=”Run Code Snippet” onclick=”window.open(‘https://coderseditor.com/?id=1206′,’_blank’)”]

a= int(input("Enter the value of a:"))

b=str(input("Enter the value of b:"))

print(type (a))

print(type (b))

b=int(b) #explicit_type_converion

c=(a+b)

print("Value of c by implicit conversion", c)

print (type (c))

Output

Enter the value of a:57
Enter the value of b:75
<class 'int'>
<class 'str'>
Value of c by implicit conversion 132
<class 'int'>

Let’s look at some common explicit type conversions

int(a base)

The int() function is used to convert the given type to an integer. ‘Base’ specifies the base in which string is if the data type is a string.

float()

The float() is used to convert the given data type to a floating-point number 

str()

The str() is used to convert an integer into a string.

complex(real,imag)

The complex()is used to convert real numbers to complex(real,imag) numbers.

bool()

the bool() is used to convert the given data type to Boolean and we can perform the Boolean operation.
