mam please upload regular vedios so many people getting benefited by ur vedios

[aishwaryagandhi]

Ma'am can't we do it in this way??

*Input*
student_marks={
"Jenney":92,
"Harry":78,
"Dimpy":56,
"Rahul":41,
"Aniket":99,
"Prem":34
}

student_grades={}

for marks in student_marks:
if student_marks[marks]>90:
grade="A+"

elif student_marks[marks]>80:
grade="A"

elif student_marks[marks]>70:
grade="B+"

elif student_marks[marks]>60:
grade="B"

elif student_marks[marks]>50:
grade="C"

elif student_marks[marks]>40:
grade="D"

else:
grade="F"

student_grades[marks]=grade

print(student_grades)

*Output*
{'Jenney': 'A+', 'Harry': 'B+', 'Dimpy': 'C', 'Rahul': 'D', 'Aniket': 'A+', 'Prem': 'F'}

Excellent explaination ma'am. Upload DAA classes please. I used to learn in your channel.

[ajaymichael]

initial_dict = {"Jenny": 92, "Harry": 78, "Surya": 62, "Rakul": 41, "Ajay": 99, "Prem": 34}
resultant_dict = dict()

for name, marks in initial_dict.items():
if marks >= 91 and marks <= 100:
resultant_dict[name] = "A+"
elif marks >= 81 and marks <= 90:
resultant_dict[name] = "A"
elif marks >= 71 and marks <= 80:
resultant_dict[name] = "B+"
elif marks >= 61 and marks <= 70:
resultant_dict[name] = "B"
elif marks >= 51 and marks <= 60:
resultant_dict[name] = "C"
elif marks >= 41 and marks <= 50:
resultant_dict[name] = "D"
else:
resultant_dict[name] = "F"

print(resultant_dict) 😀😀😀

I am learning since Feb & now 4th sem ended with python

[MyCodingDiary]

You are doing such an excellent job, keep up the great work!♥

[nemeziz_prime]

This is good, need more excercise videos like this which are practical and helpful for interviews. Thank you 🙏

[pateldev]

Btw, It's excellence videos to learn python with best explanation I have ever seen!!

[edingsonlkalwing]

maam doing hard work 1 like to banta hai plzz everyone

[pateldev]

Mam please upload atleast 2 videos everyday.

[krishnayallapanthula]

this logic can be simply implemented using dictionary comprehension as well
student_grades = {}

student_grades = {key: [val, ("A+" if val in range(91, 100) else "A" if val in range(81, 90) else "B" if val in range(71, 80) else "C" if val in range(61, 70) else "D" if val in range(51, 60) else "E" if val in range(41, 50) else "F")] for (key, val) in student_marks.items()}

print(student_grades)

of course the if else can be in a function like this

student_grades = {name: [score, calculate_grade(score)] for name, score in student_marks.items()}

print(student_grades)

[rxpnjis]

s_m={
"jenny":92,
"harry":78,
"dimpy":56,
"rahul":41,
"aniket":99,
"prem":34
}

for i in s_m:
marks = s_m[i]
if marks<40:
marks="F"
elif marks>=41 and marks<50:
marks="D"
elif marks>=51 and marks<60:
marks="C"
elif marks>=61 and marks<70:
marks="B"
elif marks>=71 and marks<80:
marks="B+"
elif marks>=81 and marks<90:
marks="A"
else:
marks="A+"
s_m[i]=marks
print(s_m)

A beautiful mind,
A beautiful career, a beautiful salary and a beautiful family?
What more do you want?

These blessings are a test, you've helped many people for their career and these videos will keep helping many more people but what about you?

Are you satisfied without knowing the truth? Are you sure that what you are following is truth?
At least, for the sake of the love you have for your family.. do some research on the one n only truth. Find the right path, it won't come to you if you don't try
