How to include first number to iterator class in python?-CodePudding

How to edit this class to obtain n0 in the PPP? I am not obtaining the initial number in the sequence. Thanks

class P():
    def __init__(self, n0):
        self.n = n0

    def __iter__(self):
        return self
    
    def __next__(self):
        if self.n == 1:
            raise StopIteration
        
        self.n = self.n - 1
        return self.n

nmax = 10
PP = P(nmax)

PPP = []

for j in PP:
    PPP.append(j) 

print(PPP)

Current output:

[9, 8, 7, 6, 5, 4, 3, 2, 1]

Desired output:

[10, 9, 8, 7, 6, 5, 4, 3, 2, 1]

CodePudding user response：

Store the value before decrementing it

def __next__(self):
    if self.n == 1:
        raise StopIteration
    num = self.n
    self.n = self.n - 1
    return num

#[10, 9, 8, 7, 6, 5, 4, 3, 2]
