3. You are designing a function foo that will be called by other applications. Because the functionality provided by your function is applicable for several -applications, the function must accept a variable list of keyworded parameters. How would you write the function signature to comply with the aforementioned needs

- def foo(bar = "1", default = "2")
- def foo(*args)
- def foo(**kwargs)
4. What is the output of the following code?

- 24
- 120
- Recursion error
- 720
5. What is the difference between %matplotlib inline and %matplotlib notebook?
- %matplotlib notebook adds interactivity to the plots created for that notebook, while %matplotlib inline sets the plots to be displayed right below the code cell that -produced them.
- %matplotlib notebook makes plots created for that notebook responsive, while %matplotlib inline sets the plots to be displayed inline, right above the code cell that -produced them.
- %matplotlib inline adds interactivity to the plots created for that notebook, while %matplotlib notebook sets the plots to be displayed right below the code cell that -produced them
- %matplotlib notebook makes plots created for that notebook responsive, while %matplotlib inline sets the plots to be displayed inline, replacing the code cell that -produced them
6. If a default port is unavailable, how do you set up a custom port (9009) to launch Jupyter Notebook?

8. Given the word "python", how would you select only the consonants found in the word? (The result is as shown below)
['p','y','t','h','n']
- [] only_consonants =[]
for i in "python":
if i not in ['a','e','i','o','u']:
continue
else:
only_consonants.append(i)
print (only_consonants)
- [] only_consonants = [ ]
for i in "python":
if i not in ["a","e","i","o","u"]:
break
else:
only_consonants.append(i)
print (only_consonants)
- [] only_consonants = [ ]
for i in "python":
if i not in ['p','y','t','h','n']:
continue
else:
only_consonants.append(i)
print (only_consonants)
- [x] only consonants = [ ]
for i in "python":
if i not in ["a","e","i","o","u"]:
continue
else:
only_consonants.append(i)

- readlines()
10. You are working on a method available under the Pandas package to detect null values in a CSV file. You spot a bug in the package's method which is also treating blank -values as null. To add the bug to the official Pandas issue tracker, what should be your next step
- Report the bug on GitHub by raising an issue and also suggesting a required fix under the package repository.
- Report the bug on Kaggle by starting a discussion under the package tag and suggesting a fix.
