Exercises - list and set¶
Let us go through some exercises related to list and set.
Get second largest integer¶
Develop a code snippet using list and set manipulation functions to get second largest element from the list.
List:
[1, 5, 2, 1, 7, 5, 7, 3]Answer: 5
# Your code should go here
Create a list for integers¶
Develop a function which take a list as argument and return a new list with only integers. You can develop this using loops.
The list might contain data with different data types.
The new list with only integers should be sorted in descending order.
The new list should only contain unique values
# You should add the logic here
def extract_integers(l):
l_ints = []
return l_ints
extract_integers([1, 'Hello', None, 5, 0.15, 1, 5]) # Answer: [5, 1]
Get top n salaries¶
Develop a function which take a list of salaries and give us top n salaries. Solve the problem with out using loops.
The function should take 2 arguments - list of salaries and the top n.
Based up on the value passed as part of second argument, you should get those many top salaries.
We should get only unique top n salaries
# You should add the logic here
def top_n_salaries(salaries, top_n):
salaries_top_n = []
return salaries_top_n
salaries = [
18732.8, 12842.28, 13391.69, 14061.23,
25509.77, 13636.95, 11841.63, 11519.12,
16719.45, 25066.37, 12842.28, 25066.37
]
top_n_salaries(salaries, 3)
# Output: [25509.77, 25066.37, 18732.8]
top_n_salaries(salaries, 5)
[25509.77, 25066.37, 18732.8, 16719.45, 14061.23]
