python - Pyspark: help filtering out any rows which have unwanted characters -


writing parquet file gives me error states " ,;{}()\n\t=" characters not allowed.

i'd eliminate rows have of these characters anywhere.

would use "like", "rlike" or else?

i have tried this:

df = df.filter(df.account_number.rlike('*\n*', '*\ *','*,*','*;*','*{*','*}*','*)*','*(*','*\t*') == false)

obviously not work. i'm unsure right regex syntax is, or if need regex in particular case.

you use rlike since it's regular expressions:

df.filter(~df.account_number.rlike("[ ,;{}()\n\t=]"))

when put characters between [] means of following characters.

i don't see why these characters wouldn't allowed in dataframe rows, there might invalid character in column names instead. can use .withcolumnrenamed() rename it.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
