While taking input from input(), you need to convert input into float and int types, if you are reading numbers.

Q. While taking input from input(), you need to convert the input into float and int types, if you are reading numbers.

(a) What built-in function do you use to convert a string into a floating-point number? Demonstrate this function by converting string '85' into a floating-point number and assigning it to a variable x.
(b) What built-in function do you use to convert a string into an integer?
(c) What happens when you try to convert a string into an integer but the string is not a number?

Answer :-

(a)

Program :-

val = input ("Enter Number :- ")
x = float (val)
print (x)
print (type (x))

Output :-

Enter Number :- 85

85.0

<class 'float'>

>>>

Enter Number :- 53.26

53.26

<class 'float'>

>>>

(b) We can use int() function to convert a string into an integer.

Program :-

val = input ("Enter Number :- ")
x = int (val)
print (x)
print (type (x))

Output :-

Enter Number :- 65

65

<class 'int'>

>>>

(C) It will give an Error : 

Enter a Number:- Path Walla

Traceback (most recent call last):
  File "\Desktop\temp.py", line 1, in <module>
    sen = int(input("Enter a Number :-"))
ValueError: invalid literal for int() with base 10: 'Path Walla'
