Today, We want to share with you python if not.In this post we will show you how to use not in python, hear for if not python we will give you demo and example for implement.In this post, we will learn about list to string python with an example.
Python If with NOT Operator
I can use logical not operator with Python Example IF condition. The statements inside if block code execute only if the value(boolean) is False or if the value(collection) is not blank.

The syntax of Example If statement with NOT logical operator is
if not value:
statement(s)
where the data value could be of data type boolean, string, list, dict, set, etc.
If data value is of boolean data type, then NOT acts a negation operator. If data value is False, not value would be True, and the statement(s) in if-block code will execute. If data value is True, not value would be False, and the statement(s) in if-block code will not execute.
If data value is of data type string, then statement(s) in if-block code will execute if string is null.
If value is of type list, then statement(s) in if-block code will execute if list is clear. The same simplification holds correct for data value of other collection datatypes: dict, set and tuple.
In summary, I can use if not declaration to conditionally execute a block code of statements only if the data value is not null or not False.
Example 1: if not – Boolean
In this program, I will use Python Example not logical operator in the boolean declaration of Python Example IF.
Program
flag = False
if not flag:
print('flag is false.')
Results
flag is false.
Example 2: Python if not – String
In this program, I will use Python Example if not declaration to dump the string only if the string is not blank.
Program
flag = ''
if not flag:
print('String is blank.')
else:
print(flag)
Results
String is blank.
Example 3: Python if not – List
In this program, I will use Python Example if not declaration to dump the list only if the list is not clear.
Program
flag = []
if not flag:
print('List is blank.')
else:
print(flag)
Results
List is blank.
Example 4: Python if not – Dictionary
In this program, I will use Python Example if not declaration to dump the dictionary only if the dictionary is not blank.
Program
flag = dict({})
if not flag:
print('Dictionary is blank.')
else:
print(flag)
Results
Dictionary is blank.
Example 5: Python if not – Set
In this program, I will use Python Example if not declaration to dump the set, only if the set is not blank.
Program
flag = set({})
if not flag:
print('Set is blank.')
else:
print(flag)
Results
Set is blank.
Example 6: Python if not – Tuple
In this program, I will use Example if not declaration to dump the tuple, only if the tuple is not blank.
Program
flag = tuple()
if not flag:
print('Tuple is blank.')
else:
print(flag)
Results
Tuple is blank.
I hope you get an idea about not logical operator along with if conditional statement.
