LEVEL 1
#01: Write a program which will find all such numbers which are divisible by 7 but are not a multiple of 5, between 2000 and 3200 (both included). The numbers obtained should be printed in a comma-separated sequence on a single line.
Solution
l=[]
for num in range (2000,3200):
if((num%7==0) and (num%5!=0)):
l.append(num)
print(*l, sep=',')#02: Write a program which can compute the factorial of a given numbers. The results should be printed in a comma-separated sequence on a single line.
Solution
def factorial(x):
if(x==0):
return 1
return factorial(x-1)*x
n=int(input())
print(factorial(n))#03: With a given integral number n, write a program to generate a dictionary that contains (i, i*i) such that is an integral number between 1 and n (both included). and then the program should print the dictionary.
Solution
d=dict()
n=int(input())
for i in range (1,n+1):
d[i]=i*i
print(d)#4 to be solved
#05: Define a class which has at least two methods: getString: to get a string from console input printString: to print the string in upper case. Also please include simple test function to test the class methods.
Solution
class inout:
def __init__(self):
self.s=""
def gestring(self):
self.s=input()
def prinstring(self):
print(self.s.upper())
strobj=inout()
strobj.gestring()
strobj.prinstring()LEVEL 2
#06: Write a program that calculates and prints the value according to the given formula: Q = Square root of [(2 * C * D)/H] Following are the fixed values of C and H: C is 50. H is 30. D is the variable whose values should be input to your program in a comma-separated sequence. Example Let us assume the following comma separated input sequence is given to the program: 100,150,180 The output of the program should be: 18,22,24
Solution
import math
c=50
h=30
value=[]
items=[x for x in input().split(',')]
for d in items:
value.append(str(int(round(math.sqrt(2*c*float(d)/h)))))
print(','.join(value))#08: Write a program that accepts a comma separated sequence of words as input and prints the words in a comma-separated sequence after sorting them alphabetically. Suppose the following input is supplied to the program: without,hello,bag,world Then, the output should be: bag,hello,without,world
Solution
items=[x for x in input().split(',')]
items.sort()
print(','.join(items))#09: Write a program that accepts sequence of lines as input and prints the lines after making all characters in the sentence capitalized. Suppose the following input is supplied to the program: Hello world Practice makes perfect Then, the output should be: HELLO WORLD PRACTICE MAKES PERFECT
Solution
lines=[]
while True:
s=input()
if s:
lines.append(s.upper())
else:
break
for sentence in lines:
print(sentence)#10: Write a program that accepts a sequence of whitespace separated words as input and prints the words after removing all duplicate words and sorting them alphanumerically. Suppose the following input is supplied to the program: hello world and practice makes perfect and hello world again Then, the output should be: again and hello makes perfect practice world
Solution
s=input()
words=[word for word in s.split(' ')]
print(' '.join(sorted(list(set(words)))))#11: Write a program which accepts a sequence of comma separated 4 digit binary numbers as its input and then check whether they are divisible by 5 or not. The numbers that are divisible by 5 are to be printed in a comma separated sequence. Example: 0100,0011,1010,1001 Then the output should be: 1010 Notes: Assume the data is input by console.
Solution
value = []
items=[x for x in input().split(',')]
for p in items:
intp=int(p,2)
if not intp%5:
value.append(p)
print(','.join(value))#12: Write a program, which will find all such numbers between 1000 and 3000 (both included) such that each digit of the number is an even number. The numbers obtained should be printed in a comma-separated sequence on a single line. Hints: In case of input data being supplied to the question, it should be assumed to be a console input.
Solution
values = []
for i in range(1000,3001):
s=str(i)
if(int(s[0])%2==0) and (int(s[1])%2==0) and (int(s[2])%2==0) and (int(s[3])%2==0):
values.append(s)
print(",".join(values))#13: Write a program that accepts a sentence and calculate the number of letters and digits. Suppose the following input is supplied to the program: hello world! 123 Then, the output should be: LETTERS 10 DIGITS 3
Hints: In case of input data being supplied to the question, it should be assumed to be a console input.
Solution
s=input()
d={"LETTERS":0, "DIGITS":0}
for i in s:
if i.isdigit():
d["DIGITS"]+=1
elif i.isalpha():
d["LETTERS"]+=1
else:
pass
print("LETTERS", d["LETTERS"])
print("DIGIT", d["DIGITS"])#14: Write a program that accepts a sentence and calculate the number of upper case letters and lower case letters. Suppose the following input is supplied to the program: Hello world! Then, the output should be: UPPER CASE 1 LOWER CASE 9
Hints: In case of input data being supplied to the question, it should be assumed to be a console input.
Solution
s=input()
d={"UPPER CASE":0, "LOWER CASE":0}
for i in s:
if i.isupper():
d["UPPER CASE"]+=1
elif i.islower():
d["LOWER CASE"]+=1
else:
pass
print("UPPER CASE", d["UPPER CASE"])
print("LOWER CASE", d["LOWER CASE"])#17: Question: Write a program that computes the net amount of a bank account based a transaction log from console input. The transaction log format is shown as following: D 100 W 200
D means deposit while W means withdrawal. Suppose the following input is supplied to the program: D 300 D 300 W 200 D 100 Then, the output should be: 500
Hints: In case of input data being supplied to the question, it should be assumed to be a console input.
Solution
total=0
while True:
s=input().split()
if not s:
break
cm,num=map(str,s)
if cm=="D":
total+=int(num)
if cm=="W":
total-=int(num)
print(total)
