Delete a variable

Use the del  keyword to delete the variable. Once we delete the variable, it will not be longer accessible and eligible for the garbage collector.

Example:

var1 = 100
print(var1) # 100

Now, let's delete var1 and try to access it again.

Example:

var1 = 100
del var1
print(var1) # wrong processing

Output:

NameError: name 'var1' is not defined
