Question: I'm trying to create a program that involves assigning a string to the variable x depending on the length of the string assigned to variable y. The amount of commas in x should be the same as the length of y.

For example if `e='h'` , `x=','`. If `e='hi'` , `x=',,'`. If `e='him'` , `x=',,,'`

By the way, I'm new to programming so I don't know this stuff.

Answer: 
Invoke `len()` on `e` to get the length of the string and multiply that length by the string `,`, assigning it to `x`:

```
e = 'him'
e_length = len(e)
x = ',' * e_length
print(x)

```

This should yield `,,,`.
Python allows you to multiply a string by a number to repeat it, which means you can do:

```
e = 'hello there'
x = ',' * len(e)

```

Which will give you:

```
',,,,,,,,,,,'

```
