QUESTIONS

Which of the following statements about Python strings is true?

Right Answer:

Strings in Python can be concatenated using the “+” operator to combine multiple strings into one.

What is the output of the following code snippet?
x = 10
y = 20
x, y = y, x
print(x, y)

Right Answer:

This code swaps the values of variables “x” and “y” using tuple unpacking. Therefore, the output will be 20 10.

What will be the output of the following code snippet?
x = "hello"
y = x.upper()
print(y)

Right Answer:

The upper() method converts all characters in a string to uppercase. Therefore, the output will be “HELLO”.

Which data type in Python is used to represent a true or false value?

Right Answer:

Booleans in Python are used to represent true or false values.

What is the output of the following code snippet?
x = [1, 2, 3]
y = x.copy()
x.append(4)
print(y)

Right Answer:

The copy() method creates a shallow copy of the list, so changes made to the original list “x” will not affect the copied list “y”. Therefore, the output will be [1, 2, 3].

What is the output of the following code snippet?
x = 3.14
print(type(x))

Right Answer:

The code snippet prints the data type of the variable “x”, which is a floating-point number. The correct type name in Python is “float”.

What will be the output of the following code snippet?
x = {"a", "b", "c"}
y = {"b", "c", "d"}
z = x & y
print(z)

Right Answer:

The & operator is used for set intersection, which returns the common elements between two sets. Therefore, the output will be {“b”, “c”}.

Which data type in Python is used to store a sequence of characters?

Right Answer:

Strings are used to store sequences of characters in Python.

What will be the output of the following code snippet?
x = 10
y = "20"
print(str(x) + y)

Right Answer:

The code converts the integer “x” to a string using the str() function and then concatenates it with the string “y”. Therefore, the output will be “1020”.

What will be the output of the following code snippet?
x = "Hello"
print(type(x))

Right Answer:

The code snippet prints the data type of the variable “x”, which is a string. The correct type name in Python is “str”.
