9. How indices in python list are denoted? L1= [99,12,3,33,"ram", "hello",122] L1[index 0] =99; L1[index (0)] =99; L1 [1] =12; L1(1) =12; Answer:C) L1 [1] =12; Explanation: The index of the python list is denoted by: - List name [index]. In the example giv...
Python Array Indices and Slices The individual elements of an array can be accessed using indices. Array indices begin at 0. This means that the first element of an array is assigned an index of 0, and each subsequent element’s index progresses from there. So, to access the first, second...
You already used one of them, the Python interactive interpreter, also known as the read-evaluate-print loop (REPL). Even though the REPL is quite useful for trying out small pieces of code and experimenting, you can’t save your code for later use. To save and reuse your code, you ...
The following code snippet illustrates how you can use a range and index to display the last six characters of a string.string str = "Hello World!"; Console.WriteLine(str[^6..]);When you execute the program, the output “World!” should appear in the console window as shown in the ...
You should use .items() to access key-value pairs when iterating through a Python dictionary. The fastest way to access both keys and values when you iterate over a dictionary in Python is to use .items() with tuple unpacking.To get the most out of this tutorial, you should have a ba...
This Python Array tutorial explains what is an Array in Python, its syntax, how to perform various operations like sort, traverse, delete etc

To replace values in a NumPy array by index in Python, use simple indexing for single values (e.g., array[0] = new_value), slicing for multiple values (array[start:end] = new_values_array), boolean indexing for condition-based replacement (array[array > threshold] = new_value), and...
Assigning the values of indices as aninttype will never throw the error. The above code will run as shown below. In conclusion, nested lists are a powerful data structure in Python, but it’s important to remember that lists can only be indexed using integers. If we encounter theTypeError...
