我写了这段代码来找到最大和最小的（int）数，但它不起作用

Question

I wrote this code to get an input of several int numbers and write the smallest and largest of them but the code does not work.

numbers=[]    
num=input('enter your number')    
Int_num=int(num)    
Int_num.append(numbers)    
print('maximum number is:',max(numbers))    
print('minimum number is:',min(numbers))

Answer 1

In order to get a sequence of numbers:

numbers = []
while True:
  number = input('Enter a number or enter q to exit: ')
  if number == 'q':
      break
  else:  
      numbers.append(int(number))

print(f'Max: {max(numbers)}, Min: {min(numbers)}')

Answer 2

Replace Int_num.append(numbers) with numbers.append(Int_num.append)

To get multiple numbers you can try:

numbers = []
last_number = input('Enter a number: ')
while last_number:
  numbers.append(int(last_number))

print(f'Max: {max(numbers)}, Min: {min(numbers)}')

Answer 3

You are trying to append a list to a integer, it should be numbers.append(Int_num) , so you will append the number Int_num to the list numbers .

Answer 4

Try this:

numbers=[]       
num=input('enter your number')

while num != "":
    Int_num=int(num)    
    numbers.append(Int_num)    
    num=input('enter your number') 

print('maximum number is:',max(numbers))    
print('minimum number is:',min(numbers))

Answer 5

The problem is line Int_num.append(numbers)
it should be numbers.append(Int_num)

Also if you put a while(True): around all but the first line you can add lots of numbers to the list (use ctrl+c to stop the program, if it's running in cmd or powershell)
