Using list

More on list

Example

my_list=[3,4,5,8,3]if(5 in my_list):  print("Yes it is Present")else:  print("NO  it is NOT Present")  

Output

Yes it is Present

Example:

my_list=[3,4,5,8,3]if(9 in my_list):  print("Yes it is Present")else:  print("NO  it is NOT Present")  

Output

NO  it is NOT Present

Example using not in

my_list=[3,4,5,8,3]if(9 not in my_list):  print("Yes it is NOT Present")else:  print("NO  it is  Present")

Output

Yes it is NOT Present

Using For Loop and range

for i in range (0,5):  print(i,end=',')

Output

0,1,2,3,4,

Using string

url='plus2net.com'if( '2' in url):  print("yes 2 is available inside")else:  print("No 2 is not available inside ") 

Output

yes 2 is available inside

We will use Dictionary

Output depends on Keys of the Dictionary ( Not Values ). If any one of the key present then in returns True otherwise False

my_dict={0:'A',1:'B'}print(1 in my_dict) # True

my_dict={0:'A',1:'B'}print('A' in my_dict) # False

my_dict={'A':'X','B':'Y','C':'Z'}print('X' in my_dict)     # Falseprint('C' in my_dict)     # Trueprint('Y' not in my_dict) # True

We will use tuple

my_tuple=(6,1,12,7)print(7 in my_tuple) # True

my_tuple=(6,1,12,7)print(8 not in my_tuple) # True
