Define the following built-in functions:

(a) abs()

(b) pow()

(c) len()

(d) type()

(a) abs() — This function is used to return an absolute value (magnitude of the number). It returns the value as an int or a float type, depending upon the given argument.

For example,

a = abs(-99)
print(a)

Output: 99

(b) pow() — This function is used to find the power 'b' raised to a specified base 'a' (i.e., aᵇ). It will return the data of type int or float, depending upon the output.

For example,

a = pow(10, 3)
print(a)

Output: 1000

(c) len() — This function returns the length or the number of items of an object such as a string, list, tuple or dictionary.

For example,

wd = "Artificial Intelligence"
print(len(wd))

Output: 23

(d) type() — This function returns the data type of elements stored in any data type depending on the arguments passed to the function.

For example,

a = 10
print(type(a))

Output: <class 'int'>
