how to use if in python code example

Example 1: python if statement

usrinput = input(">> ")
if usrinput == "Hello":
  print("Hi")
elif usrinput == "Bye":
  print("Bye")
else:
  print("Okay...?")

Example 2: elif python

The elif statement allows you to check multiple expressions for TRUE 
and execute a block of code as soon as one of the conditions evaluates
to TRUE. Similar to the else, the elif statement is optional. However,
unlike else, for which there can be at most one statement, there can 
be an arbitrary number of elif statements following an if.

if expression1:
   statement(s)
elif expression2:
   statement(s)
elif expression3:
   statement(s)
else:
   statement(s)

Example 3: if statement python

#a statement that checks if a condition is correct
#example:
x=5
if x == 5:
  print("x is 5")
else:
  print("x is not 5")

Example 4: if statement in python

#Conditionals statements in python
#'=' conditionals statements
a = 123
b = 123

if(a==b):
  print('True')
  
#<, > conditionals statements

a = 2
b = 45

if(a<b):
  print('A is smaller than B')

Example 5: if statement python

x=1; y=0; z=0;
if x==1 or y==0:
  if z=0 and x=1:
    print('Useless conditions satisfed!')

Example 6: if statement python

x=1; y=0; z=0;
if 1 in {x,y,z}:
  print('At least one variable is equal to 1')
