我正在尝试在两个文件之间进行链式比较,如果它在指定的时间间隔内打印/写出结果。
这是我到目前为止所做的。
test1文件:
A0AUZ8, DOC_PP1_RVXF_1, 8, 16, PF00149, O24930
A0AUZ9, LIG_BRCT_BRCA1_2, 127, 134, PF00533, O25336
A0AUZ9, LIG_BRCT_BRCA1_1, 127, 132, PF00533, O25336
A0AUZ9, DOC_PP1_RVXF_1, 8, 16, PF00149, O25685
A0AUZ9, DOC_PP1_RVXF_1, 8, 16, PF00149, O25155
测试2档:
results = []
with open('test1', 'r') as disorder:
for lines in disorder:
cells = lines.strip().split(',')
with open('test2', 'r') as helpy:
for lines in helpy:
blocks = lines.strip().split(',')
if blocks[0] != cells[0]:
continue
elif cells[1] <= blocks[2] and blocks[3] <= cells[2]:
results.append(blocks)
with open('test3','wt') as outfile:
for i in results:
outfile.write("%s\n" % i)
脚本本身:
func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 80 // this is your row height
}
我首选的输出是只有test3中的行,即:
在第一列中有匹配的ID
第3列和第4列中的两个数值介于test1文件中给出的值
之间我没有输出,我不确定它出了什么问题。
答案 0 :(得分:1)
它不能按预期工作的原因之一是你要比较字符串而不是数字。
然而,可能有更好的方法来做你想做的事情。假设第一个文件足够小以适合内存:
import csv
from collections import defaultdict
lookup_table = defaultdict(list)
with open('test1.txt') as f:
reader = csv.reader(f)
for row in reader:
lookup_table[row[0]].append((int(row[1]),int(row[2])))
with open('test2.txt') as a, open('results.txt', 'w') as b:
reader = csv.reader(a)
writer = csv.writer(b)
for row in reader:
record = lookup_table.get(row[0])
if record:
if record[0] <= int(row[2]) and record[1] <= int(row[3]):
writer.writerow(row)
