Calling a Non-Callable ObjectProblematic Code:number = 10result = number() Error Message:TypeError: 'int' object is not callable Solution: Here, number is an integer (int), so it cannot be called like a function. If you intended to use the variable, remove the parentheses. result = number Alternatively, if you intended to call a function, ensure you are using the correct function. def number(): ..

Multiplication Between a List and an IntegerProblematic Code: numbers = [1, 2, 3]result = numbers * numbersError Message: TypeError: can't multiply sequence by non-int of type 'list' Solution: To repeat the list, multiply it by an integer, or to concatenate two lists, use the + operator. # Repeating the list by an integerresult = numbers * 3# Concatenating two listsresult = numbers + numbers

Addition Between Incompatible TypesProblematic Code:result = "The number is: " + 5Error Message: TypeError: can only concatenate str (not "int") to strSolution: You need to convert the integer to a string before performing the addition.result = "The number is: " + str(5)Alternatively, you can use string formatting to insert the variable.result = f"The number is: {5}"

File input and output in Python are crucial for reading from and writing to files. This is typically done using the open() function.1. Opening a Fileopen() function: Used to open a file. This function takes the file path and the mode as arguments."r": Read mode (default)"w": Write mode (overwrites the file if it exists, creates a new one if it doesn’t)"a": Append mode (adds content to the end of..

Python's basic input and output operations are performed using the input() function for input and the print() function for output.1. Inputinput() function: This function allows the program to receive input from the user. It always captures the input as a string.Example:name = input("Enter your name: ")In this code, the user's name is stored in the variable name.2. Outputprint() function: This fu..

In Python, a lambda function is a small anonymous function defined with the lambda keyword. Unlike regular functions defined using def, lambda functions are typically used for short, throwaway functions that are not meant to be reused elsewhere. They are often used when you need a simple function for a short period and don’t want to formally define it.Basic SyntaxThe syntax for a lambda function..

In Python, a function is a block of code designed to perform a specific task. Functions help increase code reusability and make the structure of a program easier to understand. Functions in Python are defined using the def keyword.Basic Structure of a FunctionA function in Python has the following basic structure:python def function_name(parameter1, parameter2, ...): """Documentation string (..

Calling a Function or Module Before It's DefinedProblematic Code: greet()def greet(): print("Hello, World!")Error Message: NameError: name 'greet' is not defined Solution: You must define the function or module before calling it. def greet(): print("Hello, World!")greet()

Typo in Variable NameProblematic Code: name = "Alice"print(nam) Error Message: NameError: name 'nam' is not defined Solution: Make sure to use the correct variable name. name = "Alice"print(name)

Using an Undefined VariableProblematic Code:print(name) Error Message:NameError: name 'name' is not defined Solution: You must define the variable before using it. name = "Alice"print(name)
