hasattr()<\/a> function. The hasattr() function is used to check if an object has a specific attribute or not in Python. Here is its syntax.<\/p>\n\n\n\nhasattr(object, attribute)<\/pre>\n\n\n\nhasattr() function accepts two arguments – name of object and the name of attribute. It returns true if the attribute is present in object, else it returns false. Here is an example to demonstrate it.<\/p>\n\n\n\n
class my_class:
def __init__(self):
self.test = \"value\"
obj = my_class()
if hasattr(obj, 'test'):
print(\"test is defined in obj\")
else:
print(\"test is not defined in obj\")
## output
attribute is defined in obj<\/pre>\n\n\n\nIn the above code, we have defined a class my_class. This class has an attribute test. We create an object obj using this class. Then we call hasattr() function, that accepts two arguments. The first argument is the name of object and the second attribute is the name of the attribute.<\/p>\n\n\n\n
