Python has two ways to loop through data.<\/p>\n

\nFor Loop<\/h2>\n

The first is the for loop. The for loop is used when you know how many iterations to make.<\/p>\n

Example to loop through a dictionary using a for loop:
\nShow keys:<\/strong><\/p>\n

<\/pre>\n
\nto_do_dict = {‘a’:’groceries’, ‘b’:’laundry’, ‘c’:’wash car’, ‘d’:’vacuum’}
\nprint (“TO DO ITEM KEYS:”)
\nfor key in to_do_dict:
\n    print (key)<\/p>\n
\nShow items:<\/strong><\/p>\n
<\/pre>\n
\nto_do_dict = {‘a’:’groceries’, ‘b’:’laundry’, ‘c’:’wash car’, ‘d’:’vacuum’}
\nprint (“TO DO ITEMS:”)
\nfor key, item in to_do_dict.items():
\n    print (item)<\/p>\n
\nShow keys and items:<\/strong><\/p>\n
<\/pre>\n
\nto_do_dict = {‘a’:’groceries’, ‘b’:’laundry’, ‘c’:’wash car’, ‘d’:’vacuum’}
\nprint (“TO DO KEYS AND ITEMS:”)
\nfor key, item in to_do_dict.items():
\n    print (key, item)<\/p>\n
<\/p>\n
\nWhile Loop<\/h2>\n
The second type of loop is the while loop. This is used to do something until a condition is met.<\/p>\n
Example to loop through a dictionary using a while loop:
\nShow keys:<\/strong><\/p>\n
<\/pre>\n
\nto_do_dict = {‘a’:’groceries’, ‘b’:’laundry’, ‘c’:’wash car’, ‘d’:’vacuum’}
\ncount = 0
\nprint (“TO DO ITEM KEYS:”)
\nitems = list(to_do_dict.items())
\nwhile (count < 2):
\n    print(items[count][0])
\n    count += 1<\/p>\n
\nShow items:<\/strong><\/p>\n
<\/pre>\n
\nto_do_dict = {‘a’:’groceries’, ‘b’:’laundry’, ‘c’:’wash car’, ‘d’:’vacuum’}
\ncount = 0
\nprint (“TO DO ITEM KEYS:”)
\nitems = list(to_do_dict.items())
\nwhile (count < 2):
\n    print(items[count][1])
\n    count += 1<\/p>\n
\nShow keys and items:<\/strong><\/p>\n
<\/pre>\n
\nto_do_dict = {‘a’:’groceries’, ‘b’:’laundry’, ‘c’:’wash car’, ‘d’:’vacuum’}
\ncount = 0
\nprint (“TO DO ITEM KEYS:”)
\nitems = list(to_do_dict.items())
\nwhile (count < 2):
\n    print(items[count])
\n    count += 1<\/p>\n
