[python] TypeError: object of type 'int' has no len() error assistance needed

I am writing a piece of code for my code that when the user inputs 7 digits it multiplies the digits by 3 and 1 respectively. Here is the code;

When it goes to check if the user has entered 7 digits it gives me this error: TypeError: object of type 'int' has no len()

Well, maybe an int does not posses the len attribute in Python like your error suggests?

Try:

len(str(numbers))

Abstract:

The reason why you are getting this error message is because you are trying to call a method on an int type of a variable. This would work if would have called len() function on a list type of a variable. Let's examin the two cases:

Fail:

num = 10

print(len(num))

The above will produce an error similar to yours due to calling len() function on an int type of a variable;

Success:

data = [0, 4, 8, 9, 12]

print(len(data))

The above will work since you are calling a function on a list type of a variable;

May be it is the problem of using len() for an integer value. does not posses the len attribute in Python.

Error as:I will give u an example:

number= 1
print(len(num))

Instead of use ths,

data = [1,2,3,4]
print(len(data))
