Response:You can utilize the built-in type() function to ascertain Python variable types.
Typically, we can ascertain the variable type simply by examining the assigned value. However, there are instances where we may want to verify the variable’s type explicitly. This can be achieved by employing Python’s built-in functions and modules described below:
Approaches to Identify Data Type of Python Variables
Approach 1: Utilizing type() Function to Identify Variables in Python
When handling a variable and you wish to ascertain the type of data involved, the type() function can reveal this information. It is particularly useful during debugging, as Python does not require variables to be declared with their respective data types.
Example:
Python
Code Copied!
var isMobile = window.innerWidth “);
editor12742.setValue(decodedContent); // Set the default text
editor12742.clearSelection();
editor12742.setOptions({
maxLines: Infinity
});
function decodeHTML12742(input) {
var doc = new DOMParser().parseFromString(input, “text/html”);
return doc.documentElement.textContent;
}
// Function to copy code to clipboard
function copyCodeToClipboard12742() {
const code = editor12742.getValue(); // Get code from the editor
navigator.clipboard.writeText(code).then(() => {
jQuery(“.maineditor12742 .copymessage”).show();
setTimeout(function() {
jQuery(“.maineditor12742 .copymessage”).hide();
}, 2000);
}).catch(err => {
console.error(“Error copying code: “, err);
});
}
data: {
language: “python”,
code: code,
cmd_line_args: “”,
variablenames: “”,
action:”compilerajax”
},
success: function(response) {
var myArray = response.split(“~”);
var data = myArray[1];
jQuery(“.output12742”).html(“
"+data+"");
jQuery(".maineditor12742 .code-editor-output").show();
jQuery("#runBtn12742 i.run-code").hide();
}
})
}
function closeoutput12742() {
var code = editor12742.getSession().getValue();
jQuery(".maineditor12742 .code-editor-output").hide();
}
// Attach event listeners to the buttons
document.getElementById("copyBtn12742").addEventListener("click", copyCodeToClipboard12742);
document.getElementById("runBtn12742").addEventListener("click", runCode12742);
document.getElementById("closeoutputBtn12742").addEventListener("click", closeoutput12742);
Output:
Approach 2: Utilizing isinstance() Function to Identify Variable Type in Python
This is a built-in function that offers greater flexibility. It takes two parameters. If the first parameter is an instance of the class indicated by the second parameter, the corresponding boolean value is returned.
Example:
Python
``````html
Code Copied!
Output:
Method 3: Utilizing typing module in Python
This is the enhanced technique for identifying the data type. The typing module can be employed when dealing with extensive codebases and you need insights regarding their types.
Example:
Python
Code Copied!

Approach 4: Utilizing __class__ Attribute for Variable Type Identification in Python
In contrast to the type() function, the __class__ attribute stands out as it does not necessitate a function invocation. This attribute can directly reveal the class of the variable.
function closeOutput52842() {
var code = editor52842.getSession().getValue();
jQuery(".maineditor52842 .code-editor-output").fadeOut();
}
// Link event listeners to the buttons
document.getElementById("copyBtn52842").addEventListener("click", copyCodeToClipboard52842);
document.getElementById("runBtn52842").addEventListener("click", runCode52842);
document.getElementById("closeoutputBtn52842").addEventListener("click", closeOutput52842);
Result:
Approach 5: Implementing Type Hinting with Variables in Python
This provides an indication of the data type, and the function returns the value. This technique assists developers in understanding more readily.
function decodeHTML41955(input) {
var doc = new DOMParser().parseFromString(input, "text/html");
return doc.documentElement.textContent;
}
// Function to duplicate code to clipboard
function copyCodeToClipboard41955() {
const code = editor41955.getValue(); // Retrieve code from the editor
navigator.clipboard.writeText(code).then(() => {
// alert("Code duplicated to clipboard!");
function closeoutput41955() {
var code = editor41955.getSession().getValue();
jQuery(".maineditor41955 .code-editor-output").hide();
}
// Link event listeners to the buttons
document.getElementById("copyBtn41955").addEventListener("click", copyCodeToClipboard41955);
document.getElementById("runBtn41955").addEventListener("click", runCode41955);
document.getElementById("closeoutputBtn41955").addEventListener("click", closeoutput41955);
