To clear a variable in Python, you can simply use the del statement followed by the variable name that you want to clear. For example
My_variable = 35
print(my_variable) # Output: 35
del my_variable
print(my_variable) # Raises NameError: name 'my_variable' is not defined

clearing a variable it will clear after execute of the code because it is storing garbage values for some time if you are running with huge data for storing in to it at that we can use with the help of del
suppose if a variable x having a integer value equal to 10 then using a variable value after you use as del x .
if you are using multiple variable a,b,c and d
the use del a,b,c,d.
python is a object oriented which is high level language.

To clear a variable in Python, you can use the del statement followed by the variable name. Here's an example:
x = 10print(x) # Output: 10
del x # Clear the variable 'x'
print(x) # Raises NameError since 'x' is no longer defined
In this example, the del statement removes the reference to the variable x, effectively clearing it from memory. After the del statement, if you try to access the variable x, you will receive a NameError because it is no longer defined.
