# 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:
            break
    for line in lines:
        print(line)
