Compulsory / Elective: Public Elective Course
1. Experimental content
- Design and complete a complete application program, complete operations such as addition, subtraction, multiplication and division, with many functions and benefits
- Examine the knowledge points of basic grammar, judgment statements, loop statements, logical operations, etc.
2. Experimental process and results
By defining the functions of addition, subtraction, multiplication, and division for each calculation method, the user selects the input calculation method, then enters the number, and completes the calculation by calling the main function
Code
def add(x,y):
return x + y
def subtract(x,y):
return x - y
def multiply(x,y):
return x * y
def divide(x,y):
return x / y
while(1):
print("是否进行计算：")
choice = input("是/否：")
if choice == '否':
break
elif choice == '是':
print("输入想进行的步骤(数字)")
print("1.加法\n2.减法\n3.乘法\n4.除法:")
n = int(input())
num1 = int(input("输入第一个数："))
num2 = int(input("输入第二个数："))
if n == 1:
print(num1, '+', num2, '=', add(num1, num2))
elif n == 2:
print(num1, '-', num2, '=', subtract(num1, num2))
elif n == 3:
print(num1, 'X', num2, '=', multiply(num1, num2))
elif n == 4:
print(num1, '÷', num2, '=', divide(num1, num2))

3. Problems encountered during the experiment and the resolution process
- Question 1: Consider how to make the program perform multiple calculations
- Problem one solution: operation through loop multiple times
Others (sentiment, thinking, etc.)
There are many ways to program the Python program. For example, the experiment can be judged by a function or directly by an if statement. You can also use characters to store the previous calculation result and perform a second operation.
