Problem Formulation and Solution Overview<\/h2>\n

If you print all values from a dictionary in Python using print(dict.values())<\/code>, Python returns a dict_values<\/code> object, a view of the dictionary values. The representation prints the keys enclosed in a weird dict_values(...)<\/code>, for example: dict_values([1, 2, 3])<\/code>.<\/p>\n

Here’s an example:<\/p>\n

my_dict = {'name': 'Carl', 'age': 42, 'income': 100000}\nprint(my_dict.values())\n# dict_values(['Carl', 42, 100000])<\/pre>\n
\n
\"\"<\/figure>\n<\/div>\n
There are multiple ways to change the string representation of the values, so that the print()<\/a><\/code> output doesn’t yield the strange dict_values<\/code> view object. <\/p>\n<\/p>\n
Method 1: Convert to List<\/h2>\n
An easy way to obtain a pretty output when printing the dictionary values without dict_values(...)<\/code> representation is to convert the dict_value<\/code> object to a list using the list() <\/a><\/code>built-in function. For instance, print(list(my_dict.value()))<\/code> prints the dictionary values as a simple list<\/a>.<\/p>\n
Here’s an example:<\/p>\n
my_dict = {'name': 'Carl', 'age': 42, 'income': 100000}\nprint(list(my_dict.values()))\n# ['Carl', 42, 100000]<\/pre>\n
So far, so simple. Read on to learn or recap some important Python features and improve your skills. There are many paths to Rome! \"\ud83c\udfdb\"<\/p>\n
Method 2: Unpacking<\/h2>\n
An easy and Pythonic way to print a dictionary without the dict_values<\/code> prefix is to unpack<\/a> all values into the print()<\/code> function using the asterisk operator<\/a>. This works because the print()<\/code> function allows an arbitrary number of values as input. It prints those values separated by a single whitespace character per default.<\/p>\n
Here’s an example:<\/p>\n
my_dict = {'name': 'Carl', 'age': 42, 'income': 100000}\nprint(*my_dict.values())\n# Carl 42 100000\n<\/pre>\n
It cannot get any more concise, frankly. \"\ud83d\ude42\"<\/p>\n
Of course, you can change the separator and end arguments accordingly to obtain more control of the output:<\/p>\n
my_dict = {'name': 'Carl', 'age': 42, 'income': 100000}\nprint(*my_dict.values(), sep='\\n', end='\\nThe End')<\/pre>\n
Output:<\/p>\n
Carl\n42\n100000\nThe End<\/pre>\n
Do you need even greater flexibility than this? No problem! See here: \"\u2935\"<\/p>\n
Method 3: String Join Function and Generator Expression<\/h2>\n
To convert the dictionary values to a single string object without 'dict_values'<\/code> in it and with maximal control, you can use the string.join()<\/a><\/code> function in combination with a generator expression<\/a> and the built-in str()<\/a><\/code> function. <\/p>\n
Here’s an example:<\/p>\n
my_dict = {'name': 'Carl', 'age': 42, 'income': 100000}\nprint(', '.join(str(x) for x in my_dict.values()))\n# Carl, 42, 100000<\/pre>\n
\"\ud83d\udca1\" Note<\/strong>: You can replace the comma ','<\/code> with your desired separator character and modify the representation of each individual element by modifying the expression str(x)<\/code> of the generator expression to something arbitrary complicated.<\/p>\n
See here for something crazy that wouldn’t make any sense:<\/p>\n
my_dict = {'name': 'Carl', 'age': 42, 'income': 100000}\nprint(' | '.join('x' + str(x) + 'x' for x in my_dict.values()))\n# xCarlx | x42x | x100000x<\/pre>\n
Note that you could also use the repr()<\/a><\/code> function instead of the str()<\/code> function in this example—it wouldn’t matter too much.<\/p>\n
Finally, I’d recommend you check out this tutorial to learn more how generator expressions work—many Python beginners struggle with this concept even though it’s ubiquitous in expert coders’ code bases. \"\ud83d\udc47\"<\/p>\n
