Can someone help me I always get TypeError:Can't multiply sequence by non-int of type 'str'

I am still new at python and I can't seem to get my code right. I was trying to have a FCFS that can calculate the waiting time and turn around time

def findWaitingTime(processes, n, bt, wt, at):
    service_time = [0] * n
    service_time[0] = 0
    wt[0] = 0

    for i in range(1, n):
        service_time[i] = (service_time[i - 1] + bt[i - 1])

        wt[i] = service_time[i] - at[i]
        if (wt[i] < 0):
            wt[i] = 0
        
def findTurnAroundTime(processes, n, bt, wt, tat):
    for i in range(n):
        tat[i] = bt[i] + wt[i]
    
def findavgTime(processes, n, bt, at):
    wt = [0] * n
    tat = [0] * n

    findWaitingTime(processes, n, bt, wt, at)
    findTurnAroundTime(processes, n, bt, wt, tat)

    print("Processes Burst Time Arrival Time     Waiting",
          "Time Turn-Around Time Completion Time \n")
    total_wt = 0
    total_tat = 0

    for i in range(n):
        total_wt = total_wt + wt[i]
        total_tat = total_tat + tat[i]
        compl_time = tat[i] + at[i]
        print(" ", i + 1, "\t\t", bt[i], "\t\t", at[i],
              "\t\t", wt[i], "\t\t ", tat[i], "\t\t ", compl_time)

        print("Average waiting time = %.5f "%(total_wt /n))
        print("\nAverage turn around time = ", total_tat / n) 

This is my main code where the user will input all the values:

if __name__ =="__main__":

n = int(input('Enter the total numbers of processes: '))

for i in range(n):
    processes = input('Enter the processes: ')

for i in range(n):
    burst_time = (int(input('Enter the burst time: ')))

for i in range(n):
    arrival_time = (int(input('Enter the arrival time: ')))


findavgTime(n, processes, burst_time,arrival_time)

Please also type attach a screenshot of error so we can clearly understand
