dictionary - Python- within a for loop, select item from a list within a list of list -


sorry if code bad hobbyist... done in python 3.6. cat_lists list of lists = [['1','etc1],['a', 'etc']]. beneath function called print_cat_data() after creation of var_names , cat_lists.

def print_cat_data(var_names): #print out tables of data, using lists startup_cat. using i/o               fix     open("cat_table.txt","w")as cat_table:             item_a, item_b in zip (var_names, cat_lists): #need select items cat_lists therefore need select individual items             cat_table.write(str(item_a) + ": " + '[%s]' % ', '.join(map(str, item_b)) + "\n")     open ("cat_table.txt","r")as cat_table:         print(cat_table.read()) 

under for/zip statement want select list in cat_lists , print out items in list (not print list).

  • problem 1: map returns list..
  • problem 2: nesting items in list in list in loop etc...

currently writes:

name (item var_names): [['joe', 'ben']] (list cat_lists) age: [['2', '33']] 

should write

name (item var_names):'joe', 'ben' (items list in list cat_lists) age: [['2', '33']]
