Python sum max/min program-CodePudding

I need some help creating a python program that does the following:

Example Execution:
Enter a number: 5
Enter another number, or enter to quit: 8
Enter another number, or enter to quit: -2
Enter another number, or enter to quit: 1
Enter another number, or enter to quit:
Numbers entered: 4
Sum: 12
Max: 8
Min: -2

I currently have this and I am stuck:

user_input = " "
while user_input != "":
      user_input = input("Enter a number, or nothing to quit: ")
      if user_input != "":
            user_input = int(user_input)
            user_input  = 1
            print(user_input)

Help would be much appreciated!

You can first collect the inputs in a list, and then print the results, where f-strings are handy:

lst = []
while (user_input := input("Enter a number (blank to quit): ").strip()):
    lst.append(int(user_input))

print(f"You have entered {len(lst)} numbers:", *lst)
print(f"Sum: {sum(lst)}")
print(f"Max: {max(lst)}")
print(f"Min: {min(lst)}")

If you are not familiar with walrus operator :=, then

lst = []
user_input = input("Enter a number: ").strip() # ask for input
while user_input != '': # check whether it is empty (!= '' can be omitted)
    lst.append(int(user_input))
    user_input = input("Enter a number (blank to quit): ").strip() # ask for input

Example:

Enter a number (blank to quit): 1
Enter a number (blank to quit): 2
Enter a number (blank to quit): 3
Enter a number (blank to quit):
You have entered 3 numbers: 1 2 3
Sum: 6
Max: 3
Min: 1

Detailed version:

user_inputs_values = []
user_inputs_count = 0                             # (a)
user_input = input("Enter a number: ")
user_inputs_values.append(int(user_input))
user_inputs_count  = 1                            # (a)
while True:
    user_input = input("Enter another number, or enter to quit: ")
    if not user_input:
        break
    user_inputs_values.append(int(user_input))
    user_inputs_count  = 1                        # (a)
print(f"Numbers entered: {user_inputs_count}")    # (b)
print(f"Sum: {sum(user_inputs_values)}")
print(f"Max: {max(user_inputs_values)}")
print(f"Min: {min(user_inputs_values)}")

Note that the first input message is different than the following ones.

Note using a count of entries is also possible, taas the count is equal to len(user_inputs_values). So you can remove lines marked (a) and replace line marked (b) with:

print(f"Numbers entered: {len(user_inputs_values)}")
