Answer 1

Sorry, can't upload anything to the Code Playground at the moment.

Here is what I would do:

s = '''5
Harry
37.21
Berry
37.21
Tina
37.2
Akriti
41
Harsh
39''' # change to input()

data = s.split('\n')
amount, grade_data = int(data[0]), data[1:]

grades = []

for i in range(0, len(grade_data), 2):
grades.append((grade_data[i], float(grade_data[i+1])))

grades = sorted(grades, key = lambda n: (n[1], n[0]))

second_lowest_score = grades[1][1]

print('\n'.join([val[0] for val in grades if val[1] == second_lowest_score]))

# output:
Berry
Harry

/Edit: Why did I do this? Actually you're supposed to show your attempt first

Answer 2

Please show us your attempt.

Answer 4

Could you copy and paste the assignment? I don't want to subscribe to that website

Answer 5

my_dict = dict()

user_input = input()

key, value = user_input.split(" ")

Please let me know how can i solve this

my_dict[key] = key

print(my_dict)

I am unable to parse the input to store them in the dictionary as there are more than one key names

Answer 6

Given the names and grades for each student in a Physics class of N students, store them in a nested list and print the name(s) of any student(s) having the second lowest grade.
Note: If there are multiple students with the same grade, order their names alphabetically and print each name on a new line.
Input Format
The first line contains an integer, N, the number of students.
The subsequent lines describe each student over 2N lines;
the first line contains a student's name, and the second line contains their grade.
Constraints
• 2<=N<=5
• There will always be one or more students having the second lowest grade.
Output Format
Print the name(s) of any student(s) having the second lowest grade in Physics; if there are multiple students, order their names alphabetically and print each one on a new line.

Sample input :
5
Harry
37.21
Berry
37.21
Tina
37.2
Akriti
41
Harsh
39
Sample output :
Berry
Harry
There are 5 students in this class whose names and grades are assembled to build the following list:
python students = [['Harry', 37.21], ['Berry', 37.21], ['Tina', 37.2], ['Akriti', 41], ['Harsh', 39]]
The lowest grade of 37.2 belongs to Tina. The second lowest grade of 37.21 belongs to both Harry and Berry, so we order their names alphabetically and print each name on a new line.
