how to use if statements 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: how to use an if statement in python

x = True

#Only one of the branches will ever execute
if x == True:
	print("x is true")
elif x == False:
	print("x is false")
else:
	print("x is neither true nor false")

Example 4: if syntax in python

variable_name = input("y/n? >> ")
if variable_name == "y":
	print("That's good! :) ")
# note the double equal signs. only a single equal sign will receive a Syntax error blah blah blah message.
elif variable_name == "n":
    print("That's bad! :( ")
else:
    print("You blow up for not following my instructions. Detention forever and get lost!")

Example 5: 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 6: if statement python

if (condition):
   result
    
else:
   result
