import numpy as np
# Question4:
# 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:
def Q4():
l=input().split(',')
# l=np.loadtxt("test.txt",comments="#",delimiter=',')
t=tuple(l)
print(l)
print(t)
# Question5：
# 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.
class Q5():
def get_str(self):
self.str=input()
def print_str(self):
print(self.str.upper()) # 输出大写
# Question6:
# 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.
# For example Let us assume the following comma separated input sequence is given to the program:
import math
def cal(D):
C,H = 50,30
return math.sqrt((2*C*D)/H)
def Q6():
l=input().split(',')
print(l)
l=[int(i) for i in l]
print(l)
l=[cal(i) for i in l]
print(l)
l=[round(i) for i in l]
print(l)
l=[str(i) for i in l]
print(','.join(l)) # join合并的sequence只能是字符，因此上一步需要把它变为str()
# Question 7
# 输入row,col,生成一个row*col的矩阵，这个矩阵在对应的位置上的数字为行和列的乘积
def Q7():
import numpy as np
x,y=map(int,input().split(','))
print(x,y)
arr=[]
for num in range(0,x):
tmp=[]
for j in range(0,y):
tmp.append(int(num*j))
arr.append(tmp)
print(np.asarray(arr))
# Question 8
# 输入一个逗号隔开的字母序列，输出排序后的序列
def Q8():
# input_seq=[x for x in input().split(',')]
input_seq=input().split(',')
print(input_seq)
input_seq.sort()
print(','.join(input_seq))
# Question9:
# Write a program that accepts sequence of lines as input
# and prints the lines after making all characters in the sentence capitalized.
# 输入句子序列，变为大写并打印
def Q9():
lines=[]
while(1):
s=input()
if s:
lines.append(s.upper())
else:

for line in lines:
print(line)
