Fundamentals of Python Programming

What are the basic data types in Python?

• integer, decimal, text, map

• string, number, boolean, list

• char, byte, array, object

• int, float, str, bool, list, tuple, set, dict

How do you declare a variable in Python?

• variable_name : value

• var variable_name = value

• You declare a variable in Python by using the syntax: variable_name = value.

• let variable_name = value

What is the difference between a list and a tuple in Python?

• Lists are faster than tuples in all operations.

• Tuples are created using square brackets, while lists use parentheses.

• Lists can contain only numbers, while tuples can contain any data type.

• The main difference is that lists are mutable and tuples are immutable.

Explain the use of 'if' statements in Python.

• 'if' statements in Python are used for conditional execution of code blocks.

• 'if' statements are only for looping through lists in Python.

• 'if' statements are used to define functions in Python.

• 'if' statements are used to declare variables in Python.

What is a for loop and how is it used in Python?

• A for loop is a control flow statement that allows code to be executed repeatedly based on a condition, typically used for iterating over a sequence.

• A for loop is used to define functions in Python.

• A for loop is a method for creating classes in Python.

• A for loop is a type of variable that stores data.

How do you create a function in Python?

• def function_name(parameters): # function body

• function_name(parameters) -> void: // function body

• create function_name(parameters): # function body

• function function_name(parameters) { // function body }

What is the purpose of the 'else' clause in control structures?

• The 'else' clause allows for alternative execution when the 'if' condition is false.

• The 'else' clause executes when the 'if' condition is true.

• The 'else' clause is only applicable in loops.

• The 'else' clause is used to terminate the program.

How can you handle exceptions in Python?

• Use if-else statements to handle exceptions in Python.

• Use print statements to debug exceptions in Python.

• Use try-except blocks to handle exceptions in Python.

• Ignore exceptions and continue execution.

What is the significance of indentation in Python?

• Indentation is used to define variable names in Python.

• Indentation is optional in Python and has no effect on code execution.

• Indentation is significant in Python as it defines code blocks and controls the flow of execution.

• Indentation is only used for comments in Python code.

How do you convert a string to an integer in Python?

• Use int(string) to convert a string to an integer.

• Use str(int) to convert an integer to a string.

• Apply float(string) to convert a string to a float.

• Use eval(string) to evaluate the string as an expression.
