![**Extracting a Substring from a Quote**
Consider that we have the string presented below, a quote from Thomas Edison, and we need to extract and print "Learn from it". What is the simplest sequence of function calls that will accomplish this?
```python
x = " Never get discouraged if you fail. Learn from it. Keep trying. "
```
Options:
- **a.**
```python
start = x.find('.')
end = x.find('.', start)
x = x[start+1:end]
print(x)
```
- This option attempts to find periods and slice the string between them, but it may not correctly capture the needed substring.
- **b.**
```python
x = x.split('.')
x = x[1].strip()
print(x)
```
- This option splits the string by periods and then strips whitespace from the second part. Rather effective, but not the simplest.
- **c.**
```python
x = x.strip()
x = x.split('.')
print(x[1])
```
- ***Selected Option:*** This strips leading and trailing whitespace and then splits by periods, directly accessing the desired substring.
- **d.**
```python
start = x.find('.')
end = x.find('.', start+1)
x = x[start:end]
print(x)
```
- This option also attempts to find periods similarly to option a, but it may incorrectly capture the needed substring as well.
**Explanation:** In this exercise, the selected option (c) is the simplest and most straightforward way to extract "Learn from it" by using `strip()` to remove extra spaces and `split('.')` to break the string into parts, then accessing the desired part directly via indexing.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F918808b3-3bab-4c24-a49a-fe439aaeecc0%2Fb747fe23-86e0-45c0-9d62-bdecf1519837%2F6h3g17j_processed.png&w=3840&q=75)
