The following is the use and logic of defining a def function, the isinstance() function, for in, if else, etc

movies=["the holy grail",1975,"terry jone & terry gilliam",91,
       ["graham chapman",
       ["michael palin","john cleese","terry gilliam",
            "eric idle","terry jones"]]]
def print_lol(the_list):# Define a function 
        for each_item in the_list:#for in The loop iterates through the list, from the beginning of the list to the end 
        if isinstance(each_item,list):#isinstance() detection each_item Of each item 
                                              # Isn't it list type 
            print_lol(each_item)# If so, call the function print_lol
        else:print(each_item)# If not, print this term 
print_lol(movies)# in movies The function is called in the list

 before if else Misalignment of statements results in an error
