В настоящее время я пытаюсь собрать некоторый код, который найдет совпадения значений в двух разных столбцах в двух csv файлах в пределах диапазона. Я попытался использовать приведенный ниже код, но он не выдает того, что я пытаюсь выполнить. По сути, я хочу вывести новый файл, который содержит все строки во втором файле, которые совпадают с одинаковыми столбцами в первом файле, а не объединять их вместе. Я добавил более подробные пояснения ниже моего кода. Я чувствую, что то, что я сделал до сих пор, возможно, совершенно неправильно. Что мне нужно изменить, чтобы мой код давал результаты, которые я ищу?
import csv
with open('F435W.csv') as csvF435:
readCSV1 = csv.reader(csvF435, delimiter=',')
with open("F550Mnew.csv", "w") as new_F550M:
pass
with open("F550Mnew.csv", "a") as new_F550M:
for header in readCSV1:
new_F550M.write(','.join(header)+'\n')
break
for l435 in readCSV1:
with open('F550M.csv') as csvF550:
readCSV2 = csv.reader(csvF550, delimiter=',')
for l550 in readCSV2:
if isfloat(l435[12]) and isfloat(l550[12]) and abs(float(l435[12])-float(l550[12])) < 0.002778:
if isfloat(l435[13]) and isfloat(l550[13]) and abs(float(l435[13])-float(l550[13])) < 0.002778:
new_F550M.write(','.join(l550)+'\n')
Для пояснения, каждый файл имеет столбец X и столбец Y, поэтому в основном каждая строка соответствует точке (X,Y). Кроме того, есть еще 21 столбец данных, которые не нужны для поиска совпадений, но должны быть включены в окончательный выходной файл. Я пытаюсь найти точки во втором файле, которые соответствуют точкам в первом файле в радиусе. Это потому, что я знаю, что ни одно из моих очков не будет точным совпадением. По моим данным, мой X - это столбец 13, а мой Y - это столбец 14.
Способ, которым я пытался это сделать, - найти различия между каждым X в первом файле и каждым X во втором файле (например, X1-X2) и различиями между каждым Y в первом файле и каждый Y во втором файле (например, Y1-Y2). Тогда каждая строка во втором файле, которая соответствует разностям для X и Y, которые меньше моего значения радиуса (0,0002778), будет считаться соответствием первому файлу.
К сожалению, мой код создает файл с более чем 300 000 баллов, когда мои исходные файлы имеют только 7 000 баллов. Там должно быть меньше данных, а не больше данных. Он также включает в себя множество повторений данных, когда вообще не должно быть повторений.
Спасибо за ваше время!
Пример того, как выглядят данные: я прошу прощения за длину, но я боюсь, что они не будут содержать достаточно совпадений, чтобы быть полезными, если я не включу достаточно данных.
