Description:
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.
Hints: Consider use range(#begin, #end, #step) method.
numbers = range(2000, 3201)
sorted_numbers = []
for i in numbers:
if i % 7 == 0 and i % 5 != 0:
sorted_numbers.append(i)
print(sorted_numbers)Description:
Question: Write a program which can compute the factorial of a given numbers. Suppose the following input is supplied to the program: 8 Then, the output should be:
Hints: In case of input data being supplied to the question, it should be assumed to be a console input.
Solution 1:
def fact_1(x):
b = 1
for a in range(1, x+1):
b *= a
return b
x = int(input())
print(fact_1(x))Solution 2:
def fact_2(x):
if x == 0:
return 1
return x * fact_2(x - 1)
x=int(input())
print (fact_2(x))Description:
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.
Suppose the following input is supplied to the program:
8
Then, the output should be:
{1: 1, 2: 4, 3: 9, 4: 16, 5: 25, 6: 36, 7: 49, 8: 64}
Hints:
In case of input data being supplied to the question, it should be assumed to be a console input.
Consider use dict()
def prog_1(x):
dict_ = dict()
for a in range(1, x+1):
dict_[a] = a*a
print(dict_.__str__())
prog_1(int(input()))Description:
Question:
Write a program which accepts a sequence of comma-separated numbers from console and generate a list\ and a tuple which contains every number.
Suppose the following input is supplied to the program:
34,67,55,33,12,98
Then, the output should be:
['34', '67', '55', '33', '12', '98']
('34', '67', '55', '33', '12', '98')\
Hints: In case of input data being supplied to the question, it should be assumed to be a console input. tuple() method can convert list to tuple
def prog_2():
x = input()
l = []
for a in x.split(","):
l.append(a)
print(x)
t = tuple(l)
print(l)
print(t)
prog_2()Description:
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.
Hints: Use init method to construct some parameters
class Class_1:
def __init__(self, str_):
self.str_ = str_
def getString(self):
print("Enter string:")
self.str_ = input()
return
def printString(self):
return print(self.str_)
x = Class_1("Salom, Doston")
x.printString()Description:
Write a program which takes 2 digits, X,Y as input and generates a 2-dimensional array. The element value
in the i-th row and j-th column of the array should be i*j.
Note: i=0,1.., X-1; j=0,1,¡Y-1.
Example
Suppose the following inputs are given to the program:
3,5
Then, the output of the program should be:
[[0, 0, 0, 0, 0], [0, 1, 2, 3, 4], [0, 2, 4, 6, 8]] \
Hints: Note: In case of input data being supplied to the question, it should be assumed to be a console input in a comma-separated form.
def two_dimens_arr(x, y):
l1 = []
for a in range(x):
l1.append([])
for b in range(y):
d = a * b
l1[a].append(a*b)
print(l1)
return
two_dimens_arr(4, 4)Description:
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\
Hints: In case of input data being supplied to the question, it should be assumed to be a console input.
def prog_3():
x = input()
list_ = []
for a in x.split(","):
list_.append(a)
list_.sort()
str_ = ",".join(list_)
print(list_)
print(str_)
return
prog_3()Description:
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\
Hints:
In case of input data being supplied to the question, it should be assumed to be a console input.
We use set container to remove duplicated data automatically and then use sorted() to sort the data.
def prog_4():
x = input()
set_ = set((x.split()))
list_ = [x for x in set_]
list_.sort()
print(" ".join(x for x in list_))
prog_4()Description:
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.\
Hints: In case of input data being supplied to the question, it should be assumed to be a console input.
Solution_1:
def prog_5():
x = input().split(",")
print(x)
list_ = []
for a in x:
list_.append(int(a))
list_2 = [a for a in list_ if a % 5 == 0]
print(list_2)
prog_5()Solution_2
value = []
items=[x for x in raw_input().split(',')]
for p in items:
intp = int(p, 2)
if not intp%5:
value.append(p)
print ','.join(value)Description:
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.\
For example:
2244,2888,
Not these values: 2188, 2356, 2792
Hints: In case of input data being supplied to the question, it should be assumed to be a console input.
Solution_1:
def prog_6():
n_ = []
str_num_ = ""
for a in range(1000, 3001):
str_num_ = str(a)
indicator_ = 0
for i in str_num_:
if int(i)%2 == 0:
indicator_ += 1
if indicator_ == 4:
n_.append(a)
print(n_)
return
prog_6()Solution_2:
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)Description: Write a Python program to get the Python version you are using Solution:
