Python int() Method with Examples

In the previous article, we have discussed Python id() Method with Examples
int() Method in Python:

The int() function converts the given value to an integer number.

Syntax:

int(value, base)

Parameter Values:

value: It is a number or string that can be converted into an integer number.

base: The number format is represented by a number. 10 is the default value.

Return Value:

The int() method gives:

An integer object created from a given number or string uses the default base of 10.
(No parameters) returns 0
(If base is specified) treats the string in the specified base (0, 2, 8, 10, 16)

Examples:

Example1:

Input:

Given Number = 35.5

Output:

The given number's{ 35.5 } Integer number =  35

Example2:

Input:

Given Value = 'D'
Given base = 16

Output:

The given value's { D } Integer number with given base{ 16 } = 13

Method #1: Using Built-in Functions (Static Input)

Approach:

Give the number as static input and store it in a variable.
Pass the given number as an argument to the int() function to get the given number’s Integer number.
Store it in another variable.
Print the given number’s Integer Number.
The Exit of the program.

Below is the implementation:

# Give the number as static input and store it in a variable.
gvn_numbr = 35.5
# Pass the given number as an argument to the int() function to get the
# the given numbers's Integer number.
# Store it in another variable.
rslt = int(gvn_numbr)
# Print the given number's Integer Number.
print("The given number's{", gvn_numbr,
      "} Integer number = ", rslt)

Output:

The given number's{ 35.5 } Integer number =  35

How does int() work with decimal, octal, and hexadecimal values?

Approach:

Give the value as static input and store it in a variable.
Give the base as static input and store it in another variable.
Pass the given value, base as the arguments to the int() function to get the Integer number of a given value.
Store it in another variable.
Print the Integer number of a given value.
The Exit of the program.

Below is the implementation:

# Give the value as static input and store it in a variable.
gvn_valu = '16'
# Give the base as static input and store it in another variable.
gvn_base = 8
# Pass the given value, base as the arguments to the int() function to get the
# Integer number of a given value.
# Store it in another variable.
rslt = int(gvn_valu, gvn_base)
# Print the Integer number of a given value.
print("The given value's {", gvn_valu,
      "} Integer number = ", rslt)

Output:

The given value's { 16 } Integer number =  14

Similarly, check it out for other values

gvn_valu = 'D'
gvn_base = 16
rslt = int(gvn_valu, gvn_base)
print("The given value's {", gvn_valu,
      "} Integer number = ", rslt)

Output:

The given value's { D } Integer number =  13

Method #2: Using Built-in Functions (User Input)

Approach:

Give the number as user input using the float(input()) function and store it in a variable.
Pass the given number as an argument to the int() function to get the given number’s Integer number.
Store it in another variable.
Print the given number’s Integer Number.
The Exit of the program.

Below is the implementation:

# Give the number as user input using the float(input()) function and store it in a variable.
gvn_numbr = float(input("Enter some random number = "))
# Pass the given number as an argument to the int() function to get the
# the given numbers's Integer number.
# Store it in another variable.
rslt = int(gvn_numbr)
# Print the given number's Integer Number.
print("The given number's{", gvn_numbr,
      "} Integer number = ", rslt)

Output:

Enter some random number = 250
The given number's{ 250.0 } Integer number = 250

How does int() work with decimal, octal, and hexadecimal values?

Approach:

Give the value as user input using the input() function and store it in a variable.
Give the base as user input using the int(input()) function and store it in another variable.
Pass the given value, base as the arguments to the int() function to get the Integer number of a given value.
Store it in another variable.
Print the Integer number of a given value.
The Exit of the program.

Below is the implementation:

# Give the value as user input using the input() function and store it in a variable.
gvn_valu = input("Enter some random value = ")
# Give the base as user input using the int(input()) function and store it in another variable.
gvn_base = int(input("Enter some random number = "))
# Pass the given value, base as the arguments to the int() function to get the
# Integer number of a given value.
# Store it in another variable.
rslt = int(gvn_valu, gvn_base)
# Print the Integer number of a given value.
print("The given value's {", gvn_valu,
      "} Integer number = ", rslt)

Output:

Enter some random value = B
Enter some random number = 16
The given value's { B } Integer number = 11
