is type conversion a good practice in python code example

Example 1: typecasting inpython

# Converting data type of one variable to diffrent data type is called typecasting
>>> string = '123'
>>> type(string)
<class 'str'>
>>> integer = int(string) # Converting str() to int() data type.
>>> type(integer)
<class 'int'>
>>> float_number = float(integer) # Converting int() to float() data type.
>>> type(float_number)
<class 'float'>
>>> string, integer, float_number
('123', 123, 123.0) # str, int, float

Example 2: Python Practice Problems based on type casting

num_int = 123
num_str = "456"

print("Data type of num_int:",type(num_int))
print("Data type of num_str before Type Casting:",type(num_str))

num_str = int(num_str)
print("Data type of num_str after Type Casting:",type(num_str))

num_sum = num_int + num_str

print("Sum of num_int and num_str:",num_sum)
print("Data type of the sum:",type(num_sum))
