What does the following code output?
```python
from math import ceil
number = 4.2
result = ceil(number)
print(result)
```
5
Identify the error in the following code:
```python
import random
number = random.randit(1, 10)
print(number)
```
The function `randint` is misspelled as `randit`. It should be corrected to `randint`.
What does the following code output?
```python
from math import pi
print(pi)
```
3.141592653589793
Identify the error in the following code:
```python
from math import log
number = -5
result = log(number)
print(result)
```
The `math.log()` function will raise a ValueError because it is being called with a negative number, which is not allowed for natural logarithms.
What does the following code output?
```python
from math import pow
result = pow(2, 3)
print(result)
```
8.0
Identify the error in the following code:
```python
import statistics
data = [1, 2, '3', 4, 5]
result = statistics.mean(data)
print(result)
```
The `statistics.mean()` function will raise a TypeError because the list `data` contains a string element ('3') while it expects numerical values.
What does the following code output?
```python
from random import random
print(random())
```
A pseudo-random floating point number between 0.0 and 1.0.
Identify the error in the following code:
```python
from math import factorial
number = 5.5
result = factorial(number)
print(result)
```
The `math.factorial()` function will raise a ValueError because it only accepts non-negative integer arguments, not floats.
What does the following code output?
```python
from math import floor
number = 5.9
result = floor(number)
print(result)
```
5
Identify the error in the following code:
```python
from math import exp
number = 'ten'
result = exp(number)
print(result)
```
The `math.exp()` function will raise a TypeError because it expects a numerical argument, not a string.
