Consider a situation where you want to convert a dictionary into a string; here you can use the str() function. The syntax of the method is as follows:

str(dict) 

Consider the following example:

>>> port = {80: "http", 443: "https", 23:"telnet"}
>>> port
{80: 'http', 443: 'https', 23: 'telnet'}
>>> str(port)
"{80: 'http', 443: 'https', 23: 'telnet'}"
>>>

You can easily see the double quotes around the dictionary. Let's get the max key from the dictionary, using the max() function.
