name = "Alice"
age = 30
print("My name is", name, "and I am", age, "years old.")
```
A) My name is Alice and I am 30 years old.
B) My name is and I am years old.

Explanation: The `print()` function can accept multiple arguments separated by commas. It will concatenate the arguments and print them as a single string.
-------------------------------------------------------------------------
Question 3: What does the `end` parameter in the `print()` function do?
A) It specifies the character to separate multiple items in the output.
B) It specifies the character to append at the end of the output.
C) It specifies the character to append between different print statements.
D) It specifies the character to append at the beginning of the output.
Answer: B) It specifies the character to append at the end of the output.
Explanation: By default, the `end` parameter is set to "\n", which means a newline character is appended at the end of the output. However, you can change it to any other character or an empty string to control the ending of the output.
-------------------------------------------------------------------------
Question 4: What will be the output of the following Python code?
```python
x = 10
y = 20
print(x, y, sep=" - ")
```
A) 10 - 20
B) 10 20
C) x - y
D) Error
Answer: A) 10 - 20
Explanation: The `sep` parameter in the `print()` function is used to specify the separator between different items in the output. In this code, we set `sep` to " - ", so the output will be "10 - 20".
-------------------------------------------------------------------------
Question 5: What will the following Python code print?
```python
print("Hello", end="")
print("World")
```
A) HelloWorld
B) Hello World
C) Hello\nWorld
D) Error
Answer: A) HelloWorld
Explanation: The `end` parameter, when set to an empty string, removes the newline character that would be appended at the end of the output. So, the two print statements will print their outputs without a newline in between, resulting in "HelloWorld".

python
x = 5.7
A) int
B) float
C) str
D) bool
Answer: B) float
Explanation: The presence of a decimal point in the value of x indicates that it is a floating-point number, hence the data type is "float".

python
x = "Hello"
y = "World"
result = x + y
print(result)
A) HelloWorld
B) Hello World
C) Hello + World
D) Error
Answer: A) HelloWorld
