Exporting a Pandas DataFrame to an Excel file. public static bool HasConsecutiveChars (string source, int sequenceLength) { // should check sequence length // just repeating letters return Regex.IsMatch (source," ( [a-zA-Z])\\1 {"+ (sequenceLength - 1) + "}"); // any character version // return Regex.IsMatch (source," (. The patterns we discussed above apply as well. Suppose we need a quick way to get the domain name of the email addresses. We'll use a different tactic for the name.

You might want to include "$", which means "end of the line", to be sure that the line must all consist of allowed triples. This pattern should recursively catch repeating words, so if there were 10 in a row, they get replaced with just the final occurence. But we'll start by learning basic regex commands using a few emails. If we use *, we'd be matching zero or more occurrences. Peter Otten Leif K-Brooks wrote: pattern like this: >>> re.findall (".+", "foo") # not what I want ['foo'] >>> re.findall ("something", "foo") # what I want ['f', 'oo'] This is as close as I can get: [m.group () for m in re.compile (r" (.)
