Problem solving ideas:
1. Understand that the four operations refer to the four operations of addition, subtraction, multiplication and division.
2. Do the design first, the four operations need to have addition, subtraction, multiplication and division. Learn the libraries you need to use.
3. Understand and use tools such as performance analysis.
Design implementation process:
1. Randomly generate two integers between [1,100]
2. Randomly generate an operator (+,-,*,/)
3. Print two integers and an operator as one expression
4. The operation result of the user input formula
Key code:
while True:
fh = random.randint(0, 3)
n1 = random.randint(1, 100) #number 1
n2 = random.randint(1, 100) #number 2
jsz = 0 #calculated value
if fh = = 0:
#add jsz = n1 + n2
elif fh == 1: #subtract
n1,n2 = max(n1,n2),min(n1,n2)
jsz = n1 - n2
elif fh == 2: #phase Multiply
jsz = n1 * n2
elif fh == 3: #divide
n1,n2 = max(n1,n2),min(n1,n2)
while n1 % n2 != 0:
n1 = random.randint(1, 100)
n2 = random.randint(1, 100)
n1,n2 = max(n1,n2),min(n1,n2)
jsz = int(n1 / n2)
print(n1, ysf[fh], n2, '= ', end='')
