this question has answer here: “least astonishment” , mutable default argument 30 answers code: def func(a=[]): a.append(1) print(a) func() func() func() output: [1] [1, 1] [1, 1, 1] i thought default value, list, re-assigned every time func called, , answer be: [1] [1] [1] you "thought default value, list, re-assigned everytime func called." thought wrong. if learning python should work through the official tutorial @ point. here what says default arguments : the default value evaluated once. makes difference when default mutable object such list, dictionary, or instances of classes. read tutorial details.
