Python Question

How do I just display the numbers from the list without the comma and brackets on Python

#this will ask the user to enter a 7 digit number
#then it would calculate the modulus 11 check digit
#then would show the user the complete 8 digit number




weight=[8,7,6,5,4,3,2]




number= input("Please enter your 7 digit number: ")


If the user enters more than 7 characters it will prompt the user to try again



while len(number) > 7:
number=input ("Error! Only 7 numbers allowed! Try again: ")


This puts the 7 digit number into a list



account_number=number


This converts the string in the list into a integer



account_number = [int(i) for i in account_number]


This separates the numbers into multple values every character



list(account_number)


This multiplies the account number by the weight



num1=weight[0]*account_number[0]
num2=weight[1]*account_number[1]
num3=weight[2]*account_number[2]
num4=weight[3]*account_number[3]
num5=weight[4]*account_number[4]
num6=weight[5]*account_number[5]
num7=weight[6]*account_number[6]


This adds up the all the answers above



num8=num7+num6+num5+num4+num3+num2+num1


The use of % divides the number and gives the remainder



remainder=num8%11


This generates the final check digit



check_number=11-remainder


This adds the check number to the 7 digit number (account number)



account_number.insert(7,"{0}".format(check_number))


This gives the user the total 8 digit number



print ("Your account number is {0}".format(account_number))


The account number is displayed as in this form [1,2,3,4,5,6,7]
I want it in a form where it is displayed as 1234567

Answer
>>> "".join(map(str,account_number))

This first converts ints to str, then joins them together with no spaces

example:

>>> a = [1,2,3]
>>> map(str,a)
['1', '2', '3']
>>> "".join(map(str,a))
'123'
>>> 

In your case, change to this:

account_number = "".join(map(str, account_number))
print ("Your account number is {0}".format(account_number))

while len(number) != 7:
    number=input ("Error! Only 7 numbers allowed! Try again: ")
