[Python tutorial] 12. Control flow, If...else

if ... elif ... else

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")
# a is greater than b

Short Hand If

if a > b: print("a is greater than b")

Short Hand If ... Else

Ternary Operators or Conditional Expressions

a = 330
b = 330
print("A") if a > b else print("=") if a == b else print("B") # multiful else

and

a = 200
b = 33
c = 500

if a > b and c > a:
  print("Both conditions are True")

Or

a = 200
b = 33
c = 500

if a > b or a > c:
  print("At least one of the conditions is True")

Nested If

x = 41

if x > 10:
  print("Above ten,")
  if x > 20:
    print("and also above 20!")
  else:
    print("but not above 20.")

pass Statement

if statements cannot be empty
pass statement to avoid getting an error

a = 33
b = 200

if b > a:
  pass
