#Python function to write numbers to the file
def writeNumbers(n,a,b,filename):
    f=open(filename,"w") #open file for writing
    randomNumberList=[] #list to store numbers
    #using for loop
    for i in range(0,n):
        number=random.randint(a,b) #generate random number
        randomNumberList.append(number) #store number in list
    f.write(str(randomNumberList))#write list to the file
#function to read the file and return list
def readNumbers(filename):
    f=open(filename,"r")#open file for read purpose
    return f.read() #read file contents and return
#call function with value of a , b and n and file name
#function to write numbers to the file
writeNumbers(5,1,10,"numbers.txt")
