Python Conditions


Python Conditions and if Statements
  • Equals: a == b
  • Not Equals: a != b
  • Less than: a < b
  • Less than or equal to: a <= b
  • Greater than: a > b
  • Greater than or equal to: a >= b

if Statements

If is a keyword for conditional statements.

Example:
a = 33
b = 200
if b > a:
  print("b is greater than a")

Output:
b is greater than a

Example:
a = 33
b = 200
if b > a:
print("b is greater than a")

Output:
Error
*** Indentation Error

In case of other programming language, there is a curly brackets, but in python it is different, i.e. white space.

Elif statements

If the previous statements were not true, try this condition.


Example:
a = 33
b = 33
if b > a:
  print("b is greater than a")   #this condition is not true.
elif a == b:
  print("a and b are equal")

Output:                                                                                                
a and b are equal

Else Statements

The else keyword catches anything which isn't caught by the preceding conditions

Example:
a = 200
b = 33
if b > a:
  print("b is greater than a")
elif a == b:
  print("a and b are equal")
else:
  print("a is greater than b")

Output:
a is greater than b

Example:
a = 200
b = 33
if b > a:
  print("b is greater than a")
else:
  print("b is not greater than a")

Output:
B is not greater than a

*one line if statements
a = 200
b = 33
if a > b: print("a is greater than b")

Output:
a is greater than b

Basic Operators in Python

Operators   in Python      ·        Arithmetic operators      ·        Relational operators      ·        Logical operators      ·         Bitwise  operators      ·        Assignment   operators      ·        Special operators Arithmetic operators: Arithmetic operators are used to perform mathematical operations like addition, subtraction, multiplication and division. Example: x = 10 y = 4 # Addition of numbers add = x + y # Subtraction of numbers sub = x - y # Multiplication of number mul = x * y # Division(float) of number div1 = x / y # Division(floor) of number div2 = x // y # Modulo of both number mod = x % y # print results print(add) print(sub) print(mul) print(div1) print(div2) print(mod) output: 14 6 40 2.5 2 2 Relational Operators It compares the values. It either returns  True or  False  according to the given condition. Example: a = 55 b = 33 # a &g

Python Data Types List In Python,  list   is  a  type  of container  in  Data Structures, which  is  used to store multiple data at the same time. Lists  in  Python can be created by just placing the sequence inside the square brackets[].  List  is  mutable   # Creating a List  List  =  []  print ( "Initial blank List: " )  print (List)  # Creating a List with  # the use of a String  List  =  [ 'hello world' ]  print ( " \n List with the use of String: " )  print (List)  # Creating a List with  # the use of multiple values  List  =  [ "hello" ,  "world" ,]  print ( " \n List containing multiple values: " )  print (List[ 0 ])  print (List[ 1 ])    #Creating a Multi-Dimensional List    #(By Nesting a list inside a List)  List  =  [[ 'hello' ,  'world' ] , [ 'hello' ]]  print ( " \n Multi-Dimensional List: " )  print (List)  # Creating a
