AttributeError: str object has no attribute append error occurs if we invoke append() with str type object in the place of list type object. Typically Only the specific attributes which are defined in the constructor class of the datatype can be invoked via the object of that datatype. Finally, Here is the list of attributes available in the class of the str.
['__add__', '__class__', '__contains__', '__delattr__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__',
'__getattribute__', '__getitem__', '__getnewargs__', '__gt__', '__hash__', '__init__', '__init_subclass__',
'__iter__', '__le__', '__len__', '__lt__', '__mod__', '__mul__', '__ne__', '__new__', '__reduce__',
'__reduce_ex__', '__repr__', '__rmod__', '__rmul__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__',
'capitalize', 'casefold', 'center', 'count', 'encode', 'endswith', 'expandtabs', 'find', 'format', 'format_map'
, 'index', 'isalnum', 'isalpha', 'isascii', 'isdecimal', 'isdigit', 'isidentifier', 'islower', 'isnumeric',
'isprintable', 'isspace', 'istitle', 'isupper', 'join', 'ljust', 'lower', 'lstrip', 'maketrans', 'partition'
, 'replace', 'rfind', 'rindex', 'rjust', 'rpartition', 'rsplit', 'rstrip', 'split', 'splitlines', 'startswith',
'strip', 'swapcase', 'title', 'translate', 'upper', 'zfill']
str object has no attribute append ( replication ) –
Firstly, Let’s replicate the issue with a very minimum example.
AttributeError: str object has no attribute append ( Solution ) –
As we know the root cause for this AttributeError is the unavailability of an attribute in the caller class. So There are two generic solutions. The first is replacing append with the similar intent function which is available in str type object. The Second is using a different object which has an attribute “append” define with it. Although this second approach is recommended and feasible in all types of scenarios. So to avoid confusion, we will explore the first one.
Solution: Using the concatenation operator in place of append –
Most importantly, The intent to use the append attribute is to add two str objects one after the other in the first object. To achieve this we can simply use the concatenation operator in place of an append. Here is the code for this.
As in the above example, we concatenated the str1 and str2 and assign them back to str1.
