[song] rebirth of me in py introductory training (8): module

It's not easy to create , Before reference , Point a praise , Collection , You can't pay too much attention , Family

The first 1 Turn off ： Definition of modules

Task description

stay Python During the development of the program , For the convenience of code maintenance , We can group functions , Put them in different ones .py In the document , such , Each file contains relatively little code , This .py File is called a module （Module）.

The goal of this chapter is to let readers understand and master Python Knowledge about module definition .

----------------------------------------------------------------------------------

Programming requirements

The programming task of this pass is to complete src/step1/module.py File code , Realize corresponding functions . The specific requirements are as follows ：

• Enter the side lengths of the two right angles of the right triangle a and b, It is required to calculate the bevel length ;
• Required math modular , And output the calculation result , The result retains three decimal places after the decimal point .

#  Please add code here , Enter the side lengths of the two right angles of the right triangle a and b, Calculate the bevel length 
#********** Begin *********#
j=math.sqrt(a**2+b**2)
print("%.3f"%j)



#********** End **********#

The first 2 Turn off ： Built in functions in built-in modules

Task description

We are installing Python After profile , Will also be Python The library with itself is also installed ,Python Its own library is also called Python The built-in modules .Python The built-in module of is Python An important organizational form of programming , The built-in functions in the built-in module also greatly facilitate the use of functions and other functions in the programming process .

The goal of this chapter is to let readers understand and master Python Knowledge of built-in modules and functions

---------------------------------------------------------------------------------、

Programming requirements

The programming task of this pass is to complete src/step2/built-module.py File code , Realize corresponding functions . The specific requirements are as follows ：

• Enter two positive integers a,b. It is required to judge whether there are two integers , Their sum is a, Product as b;
• If there is , The output Yes, If it does not exist , The output No.

  #  Please add code here , It is required to judge whether there are two integers , Their sum is a, Product as b
  #********** Begin *********#
  y=0;
  for i in range(a):
      if(i*(a-i)==b):
          print("Yes")
          y=1;
          break
  if(y==0):
      print("No")
