print all method and property of list object - engmoh - Oct-26-2019
lst=[1,2,5]
d=dir(lst)#content all methon and properties
for i in d:
print(lst.i)if i run i have AttributeError: 'list' object has no attribute 'i'

Use
print(getattr(list, i)) instead of print(list.i) because the name of the attribute is not 'i' but the value of the variable i.

thank you very much
can i replace "i" to value of "i" immediately without getattr() function

You may regret this but it's one of the many things that make the great consistency of the language and therefore its success. Python's designers prefer function calls over exotic syntactic constructs.
