Data Types And Numeric Types — Part 1 MCQs with Explanations

The data type for integers in Python is int.

The type() function returns the data type of the argument.

The data type for sequences of characters in Python is str.

The str() function converts a number or other data type to a string.

The data type for boolean values in Python is bool.

Floating-point numbers can be created using the decimal point notation, like 5.0.

The int() function converts a floating-point number to an integer by truncating the decimal part.

Division of two integers results in a floating-point number.

The int() function converts a string containing an integer to an integer.

str is a string data type, not a numeric data type.

The complex() function creates a complex number in the form real + imaginary.

The round() function rounds a number to a specified number of decimal places.

When an integer and a floating-point number are added, the result is a floating-point number.

The + operator concatenates strings, so "5" + "3" results in "53".

The // operator performs floor division, resulting in the quotient without the fractional part.

The imaginary part of a complex number is the coefficient of the imaginary unit j.

The int() function converts a floating-point number to an integer by truncating the decimal part.

The result of "True" is a string, not a boolean.

In Python, the abs() function returns the magnitude (modulus) of a complex number. A complex number is written in the form a + bj , where a is the real part and b is the imaginary part. The magnitude of a complex number is calculated using the formula √(a² + b²) . For the complex number 3 + 4j : Real part = 3 Imaginary part = 4 Magnitude = √(3² + 4²) = √(9 + 16) = √25 = 5 . Therefore, abs(3 + 4j) returns 5 . Hence, the correct answer is Option C: 5 .

The divmod() function returns the quotient and remainder of division.

The len() function returns the length of a sequence, such as a string.

The int() and float() functions convert strings to the respective numeric types.

The round() function rounds a number to a specified number of decimal places.

The complex() function is used to create complex numbers in Python.

Complex multiplication involves distributing and combining real and imaginary parts.

The float() function converts a string containing a number to a floating-point number.
