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!")python if else
# The if,elif,else statements check if something is True
# example
if 10 > 5:
print("Ten is greater than five")
#but let's say we write
if 10 < 5:
print("Ten is less than five")
#then this condition wouldn't be true
#so we create an "else" statement
if 10 < 5:
print("Ten is less than five")
else:
print("Ten is greater than five")
#this will print "Ten is greater than five"
# because in the if statement it checks if something is true
# we wrote 'if 10 < 5' and it's not true
# so in case the 'if' condition evaluates to false
# it executes another command
#now, the 'elif' statement
# this will check for another thing after the if statement
#example
if 10 < 5:
print("Ten is less than five")
elif 10 > 5:
print("Ten is greater than five")
# here we check if 10 is less than five
# then the statement evaluated to false because 10 is greater than 5
# so the program checked with the 'elif' (that means 'Else if')
# if the statement was true, and it was so it executed the command
#we can add as many elif statements as we want in our program
# but they always need to start with an 'if' statement
# and we can make only ONE 'else' statement at the end
# let's add an 'else' statement to the previous program
if 10 < 5:
print("Ten is less than five")
elif 10 > 5:
print("Ten is greater than five")
else:
print("Ten isn't greater or less than five")
# in this case it will print 'Ten is greater than five'
# hope this helpedPython If ... Else
