clear() function in python by R4R Team

-clear() is a python in-build function which are applicable on list and set to clear the content in list and set.

Syntax-

seq.clear()

- Here seq is may be list and set.
- clear() function are not applicable on string,tuple and other data type



program-

l=[1,2,3]
print("list is ",l)
l.clear()
print("Now list is",l)

s=set([1,2,3])
print("Set is",s)
s.clear()
print("Now set is",s)

t=tuple([1,2,3])
print("Tuple is ",t)
#t.clear()
print("Now tuple is ",t)

output-

list is [1, 2, 3]
Now list is []
Set is {1, 2, 3}
Now set is set()
Tuple is (1, 2, 3)
Now tuple is (1, 2, 3)

-In this program, we have a list and set then we clear the content by using l.clear() or s.clear().
- Here if we try to use clear() function for the tuple datatype then will give an error like AttributeError: 'tuple' object has no attribute 'clear'. so that's by we don't compile that line to ignore the error.
