python if boolean logic

def if_demo(s):
  if s == 'Hello' or s == 'Hi':
    s = s + ' nice to meet you'
  else:

  return s

python booleans

bool(True)
bool(False)

# all of the below evaluate to False. Everything else will evaluate to True in Python.
print(bool(None))
print(bool(False))
print(bool(0))
print(bool(0.0))
print(bool([]))
print(bool({}))
print(bool(()))
print(bool(''))
print(bool(range(0)))
print(bool(set()))

# See Logical Operators and Comparison Operators section for more on booleans.

Python Booleans

print(10 > 9)
print(10 == 9)
print(10 < 9)

check boolean python

a = True # dont forget capital T and F, it is case sensitive
b = False

if b == True:
  print("b is true")

if b:
  print("b is true") # this is the shorthand of the above IF statement
  
if b == False:
  print("b is false") # again dont forget True and False are case sensitive
  

check if boolean is true python

b = True
if b:
  print('b is True')
else:
  print('b is False')

Python If Boolean example

def a_bigger(a, b):
  if a > b and (a - b) >= 2:
    return True
  else:
    return False
  ## Can all be written as just
  ## return (a > b and (a - b) >= 2)
