Question 1
Level 1
Question:
Write a program which will find all such numbers which are divisible by 7 but are not a multiple of 5,
between 2000and3200(both included).
The numbers obtained should be printed in a comma-separated sequence on a single line.
Hints:
Consider use range(#begin, #end) method
# P001 solution
l=[]
for i in range(2000,3201):
if(i%7==0)and(i%5!=0):
l.append(str(i))
print(','.join(l))
#----------------------------------------#
#----------------------------------------#
Question 2
Level 1
Question:
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.
Suppose the following input is supplied to the program:
8
Then, the output should be:
40320
Hints:
In case of input data being supplied to the question, it should be assumed to be a console input.
# P002 solution

x=int(input())
print(fact(x))
#----------------------------------------#
#----------------------------------------#
Question 3
Level 1
Question:
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 1and 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:javascript上网课
In case of input data being supplied to the question, it should be assumed to be a console input. Consider use dict()
# P003 solution:
n=int(input())
d=dict()
for i in range(1,n+1):
d[i]=i*i
print(d)
#----------------------------------------#
#----------------------------------------#
Question 4
Level 1
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
# P004 solution:
values=input()
l=values.split(",")
t=tuple(l)
print(l)
print(t)
#----------------------------------------#
#----------------------------------------#
Question 5
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 InputOutString(object):
def__init__(self):
self.s =""
def getString(self):
self.s =input()
def printString(self):
print(self.s.upper())
strObj = InputOutString()
strObj.printString()
#----------------------------------------#
#----------------------------------------#
Question 6
Level 2
Question:
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 is50. H is30.
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
Hints:
If the output received is in decimal form, it should be rounded off to its nearest value
(for example,if the output received is26.0, it should be printed as26)
In case of input data being supplied to the question, it should be assumed to be a console input. # P006 solution
import math
c, h, value =50,30,[]
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))
#----------------------------------------#
#----------------------------------------#
Question 7
Level 2
Question:
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.
# P007 solution
input_str =input()
dimensions =[int(x)for x in input_str.split(',')]
rowNum = dimensions[0]
colNum = dimensions[1]
multilist =[[0for col in range(colNum)]for row in range(rowNum)]
for row in range(rowNum):
for col in range(colNum):
multilist[row][col]= row*col
print(multilist)
#----------------------------------------#
#----------------------------------------#
Question 8
Level 2
Question:
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:表单大师为什么没有组合单选
In case of input data being supplied to the question, it should be assumed to be a console input.
# P008 solution:
inject
items =[ x for x in input().split(',')]
items.sort()
print(','.join(items))
#----------------------------------------#
#----------------------------------------#
Question 9
Level 2
Question£º
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
Hints:
In case of input data being supplied to the question, it should be assumed to be a console input.
lines =[]
while True:
s =input()
if s:
lines.append(s.upper())
else:
break;
for sentence in lines:
print(sentence)

Question 10
Level 2
Question:
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.
Solution:
s =input()
words =[ word for word in s.split(' ')]
print(' '.join(sorted(list(set(words)))))

Question 11
Level 2
Question:
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
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:
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))
