python - Issue with reading partial header CSV using pandas.read_csv -


i'm trying read csv file using pandas.read_csv when files header not full, i.e., columns have names, others empty.
when reading data frame using .iloc columns header not have names. reason columns not have names column size variable , did not assign name each column.

here's example of code, input file , output

dataframe = pandas.read_csv('filename.csv',\                             sep = ",",\                             header = 0) dataframe = dataframe.iloc[::] dataset = dataframe.values[:,0:]

input file:

a b c            3 5 0      1    2   3  3   5   4      5    6   7  3   5   8      9    10  11  3   5   12     13   14  15

dataset output:

dataset = [[1,2,3][5,6,7][9,10,11][13,14,15]]

how can dataframe use entire array (without header)?

i think need .values numpy ndarray.

from io import stringio  csv_file = stringio("""a b c 3 5 0 1 2 3 3 5 4 5 6 7 3 5 8 9 10 11 3 5 12 13 14 15""")  df = pd.read_csv(csv_file,sep='\s',engine='python') df.values

output:

array([[ 1,  2,  3],        [ 5,  6,  7],        [ 9, 10, 11],        [13, 14, 15]])

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 <...
