Type casting:
- In computer science, type conversion, type casting, type coercion, and type juggling are different ways of changing an expression from one data type to another.
- In Python input() function the input taken by the user is a string.
- If we want to take a integer as an input then we have to convert the input into the integer. for this we can use int() function in python.
int function:
The int() function converts the specified value into an integer number.
for example,
i have to string variable and we want to add together then it will generally concatenate both the value .
Now if we want to add them because 12 and 13 is simple an integer value and after adding it 12+13=25. here we can use int() function to convert '12'(string 12) into 12(integer 12).
Syntax : int(x)
x='12'
print(type(x))
Output- <class str>
For converting into an int value
int_value=int(x)
print(type(int_value))
output - <class int>
Similarly you can convert y into an integer value.
Now add both and print
- This is generally known as type cast (converting an expression of one data type into other)
float() function:
- The float() method is used to return a floating point number from a number or a string.
- As we convert a variable into int similarly we can type cast a variable into float.
- Syntax: float(x)
- floating numbers are like 12.23 ,34.00,123.9 etc means all number which contain decimal For example
x=12
print(type(x)
y=float(x)
print(type(y)
print(x," is " ,type(x)," value")
print(y," is ",type(y)," value")
Output
<class int>
<class float>
12 is <class int> value
12.0 is <class float> value
There are too many inbuilt function for type casting in python like str(),list(),dict(),tuple(),set() etc i will discussed this all in upcoming tutorials.
If you have any problem then put it in the comment box.
Thank you
