Getting missing postional argument self error : Why do i get the error missing 1 required positional argument self when I call inp() on the object.

process=[]
class Process:

    def __init__(self):
        self.no=no
        self.at=at
        self.bt=bt
    def inp(self):
        ar=int(input('Enter arrival time'))
        bt=int(input('Enter burst time'))



x=int(input('Enter the no. of processes'))
for i in range(x):
    process.append(Process)
    q.no=i

for x in process:
    x.inp()
