# Python – Append Dictionary Keys and Values ( In order ) in dictionary

Given a dictionary, perform append of keys followed by values in list.

Input : test_dict = {“Gfg” : 1, “is” : 2, “Best” : 3}
Output : [‘Gfg’, ‘is’, ‘Best’, 1, 2, 3]
Explanation : All the keys before all the values in list.

Input : test_dict = {“Gfg” : 1, “Best” : 3}
Output : [‘Gfg’, ‘Best’, 1, 3]
Explanation : All the keys before all the values in list.

Method #1 : Using list() + keys() + values()

This is one of the ways in which this task can be performed. In this, we extract keys and values using keys() and values(), convert then to list using list() and perform append in order.

## Python3

 `# Python3 code to demonstrate working of  ` `# Append Dictionary Keys and Values ( In order ) in dictionary ` `# Using values() + keys() + list() ` ` `  `# initializing dictionary ` `test_dict ``=` `{``"Gfg"` `: ``1``, ``"is"` `:  ``3``, ``"Best"` `: ``2``} ` ` `  `# printing original dictionary ` `print``(``"The original dictionary is : "` `+` `str``(test_dict)) ` ` `  `# + operator is used to perform adding keys and values ` `res ``=` `list``(test_dict.keys()) ``+` `list``(test_dict.values()) ` ` `  `# printing result  ` `print``(``"The ordered keys and values : "` `+` `str``(res))  `

Output

```The original dictionary is : {'Gfg': 1, 'is': 3, 'Best': 2}
The ordered keys and values : ['Gfg', 'is', 'Best', 1, 3, 2]
```

Method #2 : Using chain() + keys() + values()

This is one of the ways in which this task can be performed. In this, we bind keys with values together in order using chain().

## Python3

 `# Python3 code to demonstrate working of  ` `# Append Dictionary Keys and Values ( In order ) in dictionary ` `# Using chain() + keys() + values() ` `from` `itertools ``import` `chain ` ` `  `# initializing dictionary ` `test_dict ``=` `{``"Gfg"` `: ``1``, ``"is"` `:  ``3``, ``"Best"` `: ``2``} ` ` `  `# printing original dictionary ` `print``(``"The original dictionary is : "` `+` `str``(test_dict)) ` ` `  `# chain() is used for concatenation ` `res ``=` `list``(chain(test_dict.keys(), test_dict.values())) ` ` `  `# printing result  ` `print``(``"The ordered keys and values : "` `+` `str``(res))  `

Output

```The original dictionary is : {'Gfg': 1, 'is': 3, 'Best': 2}
The ordered keys and values : ['Gfg', 'is', 'Best', 1, 3, 2]
```
