It means that data is stored and transferred using a script (executable) file comprised of text in a computer language. Python has a built-in library named json that handles JSON. In order to use this feature, we must first load the json package into our Python script. The text in JSON is represented by a quoted-string, which contains the value in the key-value mapping within flower braces { }.<\/p>\n<p><strong>Example:<\/strong><\/p>\n<pre>{\r\n  \u00a0 \"data\": [\r\n \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0{\r\n  \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \"ID\": \"1\",\r\n  \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \"NAME\": \"Dhoni\",\r\n  \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \"SALARY\": \"100000\"\r\n \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0},\r\n \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0{\r\n  \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \"ID\": \"2\",\r\n  \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \"NAME\": \u201cVirat\u201d,\r\n  \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \"SALARY\": \"90000\"\r\n \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0}\r\n  \u00a0 \u00a0]\r\n}<\/pre>\n<div>\n<div><strong>Get the API Key from the URL:<\/strong><\/div>\n<div><a href=\"https:\/\/exchangeratesapi.io\/documentation\/\">https:\/\/exchangeratesapi.io\/documentation\/<\/a><\/div>\n<div><\/div>\n<\/div>\n<h2>Extracting a Single Value from JSON Response Using API Call in Python<\/h2>\n<p><strong>Approach:<\/strong><\/p>\n<ul>\n<li>Import parse from urllib module using the import keyword<\/li>\n<li>Import requests module using the import keyword<\/li>\n<li>Declare the base URL using the API key variable.<\/li>\n<li>Below is the base URL whereas &#8216;0f215802f0c83392e64ee40d&#8217; is api key<\/li>\n<li>Give some random string(here currency) as user input using the input() function and store it in a variable.<\/li>\n<li>Give the other random string as user input using the input() function and store it in another variable.<\/li>\n<li>Add both the currencies separated by the &#8216;\/&#8217; symbol to the base URL path to fetch the results.<\/li>\n<li>Add the above path to the base URL and create the final URL.<\/li>\n<li>Send an API request to the server and retrieve the data.<\/li>\n<li>Get the conversion rate from the JSON data by accessing the key conversion_rate and store it in a variable<\/li>\n<li>Print the Conversion Rate.<\/li>\n<\/ul>\n<p><strong>Below is the implementation:<\/strong><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"python\"># Import parse from urllib module using the import keyword \r\nimport urllib.parse\r\n# Import requests module using the import keyword \r\nimport requests\r\n# Declare the base url using the API key variable.\r\n# Below is the base url whereas '0f215802f0c83392e64ee40d' is api key\r\nbaseUrl= \"https:\/\/v6.exchangerate-api.com\/v6\/0f215802f0c83392e64ee40d\/pair\/\"\r\n# Give some random string(here currency) as user input using the input() function\r\n# and store it in a variable.\r\nprint(\"Enter Some Random First Currency Value say (USD,INR) =\")\r\nfirstcurrency=input()\r\n# Give the other random string as user input using the input() function\r\n# and store it in another variable.\r\nprint(\"Enter Some Random Second Currency Value say (USD,INR) =\")\r\nsecondcurrency=input()\r\n# Add both the currencies separated by '\/' symbol to the base url path to fetch the results.\r\nvalue = firstcurrency+\"\/\"+secondcurrency\r\n# Add the above path to the base url and create the final url\r\nfinal_url = baseUrl+value\r\n# Send an API request to the server and retrieve the data.\r\njson_data = requests.get(final_url).json()\r\n# Get the conversion rate from the json data by accessing the key conversion_rate and store it in a variable\r\nresultValue = json_data['conversion_rate']\r\n# Print the Conversion Rate\r\nprint(\"1 \"+firstcurrency+\" = \",resultValue,secondcurrency)\r\nprint(\"Conversion rate from \"+firstcurrency+\" to \"+secondcurrency+\" = \",resultValue)<\/pre>\n<p><strong>Output:<\/strong><\/p>\n<pre>Enter Some Random First Currency Value say (USD,INR) =\r\nEUR\r\nEnter Some Random Second Currency Value say (USD,INR) =\r\nINR\r\n1 EUR = 83.8568 INR\r\nConversion rate from EUR to INR = 83.8568<\/pre>\n","protected":false},"excerpt":{"rendered":"<p>In this Python article, let us look at how to use Python to obtain single data or single values from JSON.
