python logical operators

not 
and 
or

|= operator python

>>> s1 = {"a", "b", "c"}
>>> s2 = {"d", "e", "f"}

>>> # OR, | 
>>> s1 | s2
{'a', 'b', 'c', 'd', 'e', 'f'}
>>> s1                                                     # `s1` is unchanged
{'a', 'b', 'c'}

>>> # In-place OR, |=
>>> s1 |= s2
>>> s1                                                     # `s1` is reassigned
{'a', 'b', 'c', 'd', 'e', 'f'}

operators in python

a = 3
b = 4

# Arithmetic Operators
print("The value of 3+4 is ", 3+4)
print("The value of 3-4 is ", 3-4)
print("The value of 3*4 is ", 3*4)
print("The value of 3/4 is ", 3/4)

# Assignment Operators
a = 34
a -= 12
a *= 12
a /= 12
print(a)

# Comparison Operators
# b = (14<=7)
# b = (14>=7)
# b = (14<7)
# b = (14>7)
# b = (14==7)
b = (14!=7)
print(b)

# Logical Operators
bool1 = True
bool2 = False
print("The value of bool1 and bool2 is", (bool1 and bool2))
print("The value of bool1 or bool2 is", (bool1 or bool2))
print("The value of not bool2 is", (not bool2))

Or Operator In Python

if 1==1 or 1==2:
    print("this is true")
#this is distinct from the || seen in some other languages

python logical operators code

children_above_five= True
have_good_health= True
if children_above_five and have_good_health:
    print("Eligible to get admission in Primary school.")
children_above_five= True
have_good_health= False
if children_above_five or have_good_health:
    print("Eligible to get admission in Primary school.")
children_above_five= True
have_good_health= False
if children_above_five and not have_good_health:
    print("Eligible to get admission in Primary school.")

using in as a logical operator in python

fruit = 'banana'
print('n' in fruit)     # Output: True
print('m' in fruit)     # Output: False
print('nan' in fruit)   # Output: True
if 'b' in fruit:
    print('Found it')   # Output: Found it

in and not in operators python

exactly on which containers can the in operator be applied?
Generally the rule of thumb is (not a fact but a doctrine):
if container is iterable => in can be applied 
 ex. of such containers- (str, list, tuple, set and dict)
#note1:
by iterable i mean we can iterate like this:
for x in list_object: or for y in dict_obj:
#note2:
not in operator just have opposite definition to that of in 
but above rule of thumb is true for not in as well ofcourse.
