Write a program in Python that repeatedly asks the user to input Student's Name and Class and store it in a dictionary D, whose keys are Student's Name and values are Student's Class. Then display the dictionary

D = {}

while True:

    name = input("Enter Student's Name: ")

    student_class = input("Enter Student's Class: ")

    D[name] = student_class

    choice = input("Do you want to add another student? (yes/no): ")

आइये हम स्वयं को "Re-Routing" मोड पर रखें

Life Lesson छुपा है Google Maps में, पढ़िए ज़रूर 👇

री-रूटिंग :

Re-Routing : 

क्या आपने गौर किया है कि अगर आप गलत मोड़ लेते है, तो Google मानचित्र कभी भी चिल्लाता नहीं है, निंदा या आपको डांटता नहीं है।

यह कभी अपनी आवाज ऊँची नहीं करता और न ही ये कहता है, "आपको आखिरी क्रॉसिंग पर बाएं जाना था, बेवकूफ! अब आपको लंबा रास्ता तय करना होगा और इसमें आपको बहुत अधिक समय लगने वाला है और आपको देर होने वाली है

ध्यान दें

"अगर उसने ऐसा किया, तो संभावना काफी है कि हम में से बहुत से लोग इसका इस्तेमाल करना बंद कर सकते हैं"

Google केवल "री-रूट" करता है, और आपको वहां पहुंचने का अगला सबसे अच्छा तरीका दिखाता है

इसकी प्राथमिक रुचि आपको अपने लक्ष्य तक पहुँचाने में है, न कि आपको गलती करने के लिए बुरा महसूस कराने में

इसी में, बहुत बढ़िया सबक है।

अपनी निराशा और क्रोध को उन लोगों पर उतारना आसान है, जिन्होंने गलती की है, विशेष रूप से उन लोगों पर जो हमारे करीबी और परिचित हैं, लेकिन सबसे अच्छा विकल्प समस्या को ठीक करने में मदद करना है, दोष देना नहीं।

क्या आपके पास हाल ही में री-रूटिंग क्षण थे ?

औरों के साथ भी और अपनों के साथ भी ?

अपने बच्चों, जीवनसाथी, टीम के साथी और उन सभी लोगों के लिए Google मानचित्र बनें, जो आपके लिए मायने रखते हैं और जिनकी आपको परवाह है।

आइये हम स्वयं को "Re-Routing" मोड पर रखें, जीवन को सृजनात्मक और सकारात्मक बनाये।

6. A school stores records of Class XII students using a list that contains multiple lists as its elements.

 A school stores records of Class XII students using a list that contains multiple lists as its elements. The structure of each such element is [Student_Name, Marks, MainSubject]. Crate user-defined functions to perform the operations as mentioned below:

(a) Push_student(): To push the Student_Name and Marks of all those students, who have Science as MainSubject, into a Stack StudentInfo

(b) Pop_student(): To delete all items (one at a time) from the stack StudentInfo in LIFO order and display them. Also display "Empty Stack" when there are no items remaining in the stack.

For Example:

If the stored information is:

[['Akansha',98,"Mathematics"],["Priti",96,"Science"],["Garima",99,"Science"],["Ayushi",78,"English"]]

The stack should contain:

[['Priti', 96], ['Garima', 99]]

The output should be:

["Garima",99]

["Priti",96]

Empty Stack

Solution:

def Push_student():

    for S in L:

        if S[2]=="Science":

            StudentInfo.append([S[0],S[1]])

    print(StudentInfo)

    

def Pop_student():

    while StudentInfo!=[]:

        print(StudentInfo.pop())

    else:

        print("Stack is Empty")

Push_student()

Pop_student()

8. Write a program in Python to input 5 words and push them one by one into a list named All.

  Write a program in Python to input 5 words and push them one by one into a list named All.

The program should then use the function PushNV() to create a stack of words in the list NoVowel so that it store only those words which do not have any vowel present in it, from the list All.

Thereafter, pop each word from the list NoVowel and display the popped word. When the stack is empty display the message 'EmptyStack'.

For Example:

If the words accepted and pushed into the list All are

['DRY','LIKE','RHYTHM','WORK','GYM']

Then the stack NoVowel should store

['DRY','RHYTHM','GYM']

And the output should be displayed as

GYM 

RHYTHM 

DRY 

EmptyStack

Solution:

Words=[]

for i in range(5):

    w=input("Enter any word: ")

    Words.append(w)

print(Words)

Stk=[]

V='aeiouAEIOU'

def  PushNV():

    for w in Words:

        c=0

        for v in V:

            if v in w:

                c=c+1

        if c==0:

            Stk.append(w)

def PopNV():

    while Stk!=[]:

        print(Stk.pop())

    else:

        print("Stack is Empty")

PushNV()

5. Priyanka has created a dictionary 'emeployee_data' containing EmpCode and Salary as key value pairs

 Priyanka has created a dictionary 'emeployee_data' containing EmpCode and Salary as key value pairs for 5 Employees of Cyber Intratech. Write a program, With separate user defined function, as mentioned below, to perform the following operations:

(a)  push_emp(): Push all those EmpCode, where the Salary is less than 25000, from the dictionary into a stack 'stk_emp'

(b)  pop_emp(): Remove all the elements from the stack, one at a time, in a Last-In-First-Out(LIFO) manner and displays them. It also displays 'Stack is empty' once all the element have been removed.

For Example:

If the sample content of the dictionary is as follows:

{'E001':15000,'E002':27000,'E003':30000,'E004':15000,'E005':19000}, then the stack 'stk_emp' will contain EmpCode E001, E004, E005 after push_emp(). pop_emp() will pop and display employee record in LIFO fashion and display 'Stack is empty' at last.

Solution:

stk_emp=[]

employee_data={'E001':15000,'E002':27000,'E003':30000,'E004':15000,'E005':19000}

def push_emp():

    for k in employee_data.keys():

        if employee_data[k]<25000:

            stk_emp.append(k)

def pop_emp():

    while stk_emp!=[]:

        print(stk_emp.pop())

    else:

        print("Stack is Empty")

push_emp()

pop_emp()

data=[['Delhi',110001],['Sonipat',152364],['Khatauli',251201]]

def Push_City():

    for i in data:

        City.append(i)

    

def Display_City():

    L=len(City)

    print(City[L-1])

Push_City()

Display_City()

2. A School has created a dictionary containing top players and their runs as key value pairs of cricket team.

 A School has created a dictionary containing top players and their runs as key value pairs of cricket team. Write a program with separate user defined functions to perform the following operations:

(a)    Push the name of the players(Keys) of the dictionary into a stack, where the corresponding runs (value) is greater than 49.

(b)    Pop and display the content of the stack.

For Example
