Python regex multiple repeat error

regular expressions (regex) in python allow you to search for patterns in strings using a special syntax. one common error that you may encounter while using regex is the "multiple repeat" error. this error occurs when you attempt to quantify a quantifier, which means you are trying to repeat a quantified expression that is already being repeated.

for example, let's say you want to match a string that contains 3 to 5 consecutive lowercase letters. you might try to use the following regex pattern: `([a-z]{3,5}){2}`. this pattern is trying to repeat the expression `[a-z]{3,5}` twice, which is not allowed and will result in a "multiple repeat" error.

here is an example code that will produce a "multiple repeat" error:

when you run this code, you will encounter the following error:

to fix this error, you need to modify your regex pattern to avoid quantifying a quantifier. in this case, you can simply remove the outer quantifier and use the following pattern to match 3 to 5 consecutive lowercase letters:

by removing the outer quantifier, you will no longer encounter the "multiple repeat" error and your regex pattern will work as intended.
