Course Overview
Python Function
The Python built-in functions are defined as the functions whose functionality is pre-defined in Python. The python interpreter has several functions that are always present for use. These functions are known as Built-in Functions. There are several built-in functions in Python which are listed below:
Python abs() Function
The pythonabs()function is used to return the absolute value of a number. It takes only one argument, a number whose absolute value is to be returned. The argument can be an integer and floating-point number. If the argument is a complex number, then, abs() returns its magnitude.
Python abs() Function Example
-
# integer number
integer = -20
print(‘Absolute value of -40 is:’, abs(integer))# floating number
floating = -20.83
print(‘Absolute value of -40.83 is:’, abs(floating))
Output:
-
Absolute value of -20 is: 20
Absolute value of -20.83 is: 20.83
Python all() FunctionThe pythonall()function accepts an iterable object (such as list, dictionary, etc.). It returns true if all items in passed iterable are true. Otherwise, it returns False. If the iterable object is empty, the all() function returns True.Python all() Function Example
-
# all values true
k = [1, 3, 4, 6]
print(all(k))# all values false
k = [0, False]
print(all(k))# one false value
k = [1, 3, 7, 0]
print(all(k))# one true value
k = [0, False, 5]
print(all(k))# empty iterable
k = []
print(all(k))
Output:
- True
False
False
False
True
Python bin() FunctionThe pythonbin()function is used to return the binary representation of a specified integer. A result always starts with the prefix 0b.Python bin() Function Example
-
x = 10
y = bin(x)
print (y)
Output:
- 0b1010
Python bool()
The pythonbool()converts a value to boolean(True or False) using the standard truth testing procedure.
Python bool() Example
- test1 = []
print(test1,’is’,bool(test1))
test1 = [0]
print(test1,’is’,bool(test1))
test1 = 0.0
print(test1,’is’,bool(test1))
test1 = None
print(test1,’is’,bool(test1))
test1 = True
print(test1,’is’,bool(test1))
test1 = ‘Easy string’
Output:
- [] is False
[0] is True
0.0 is False
None is False
True is True
Easy string is True
Python bytes()
The pythonbytes()in Python is used for returning abytesobject. It is an immutable version of the bytearray() function.
It can create empty bytes object of the specified size.
Python bytes() Example
- string = “Hello World.”
array = bytes(string, ‘utf-8’)
print(array)
Output:
- b ‘ Hello World.’
Python callable() Function
A pythoncallable()function in Python is something that can be called. This built-in function checks and returns true if the object passed appears to be callable, otherwise false.
Python callable() Function Example
- x = 8
print(callable(x))
Output:
- False
Python compile() FunctionThe pythoncompile()function takes source code as input and returns a code object which can later be executed by exec() function.Python compile() Function Example

code = compile(code_str, ‘sum.py’, ‘exec’)
print(type(code))
exec(code)
exec(x)
Output:
- <class ‘code’>
sum = 15
Python exec() Function
The pythonexec()function is used for the dynamic execution of Python program which can either be a string or object code and it accepts large blocks of code, unlike the eval() function which only accepts a single expression.Python exec() Function Example
- x = 8
exec(‘print(x==8)’)
exec(‘print(x+4)’)
Output:

Python next() FunctionPythonnext()function is used to fetch next item from the collection. It takes two arguments, i.e., an iterator and a default value, and returns an element.
This method calls on iterator and throws an error if no item is present. To avoid the error, we can set a default value.Python next() Function Example
- number = iter([256, 32, 82]) # Creating iterator
# Calling function
item = next(number)
# Displaying result
print(item)
# second item

# creating a tuple from a dictionary
t1 = tuple({4: ‘four’, 5: ‘five’})
print(‘t1=’,t1)
Output:
- t1= ()
t2= (1, 6, 9)
t1= (‘J’, ‘a’, ‘v’, ‘a’)
t1= (4, 5)
Python type()The pythontype()returns the type of the specified object if a single argument is passed to the type() built in function. If three arguments are passed, then it returns a new type object.Python type() Function Example
- List = [4, 5]
print(type(List))Dict = {4: ‘four’, 5: ‘five’}
print(type(Dict))class Python:
a = 0InstanceOfPython = Python()
print(type(InstanceOfPython))
Output:
- <class ‘list’>
<class ‘dict’>
<class ‘__main__.Python’>
Python vars() functionThe pythonvars()function returns the __dict__ attribute of the given object.Python vars() Function Example
- class Python:
def __init__(self, x = 7, y = 9):
self.x = x
self.y = yInstanceOfPython = Python()
print(vars(InstanceOfPython))
Output:
- {‘y’: 9, ‘x’: 7}
Python zip() FunctionThe pythonzip()Function returns a zip object, which maps a similar index of multiple containers. It takes iterables (can be zero or more), makes it an iterator that aggregates the elements based on iterables passed, and returns an iterator of tuples.Python zip() Function Example
- numList = [4,5, 6]
strList = [‘four’, ‘five’, ‘six’]# No iterables are passed
result = zip()# Converting itertor to list
resultList = list(result)
print(resultList)# Two iterables are passed
result = zip(numList, strList)# Converting itertor to set
resultSet = set(result)
print(resultSet)
Output:
- []
{(5, ‘five’), (4, ‘four’), (6, ‘six’)}
