在python中的另一个文件行中查找模式
我正在学习python,因此我有两个包含大量行的文件: 文件1在python中的另一个文件行中查找模式,python,database,loops,file,pattern-matching,Python,Database,Loops,File,Pattern Matching,我正在学习python,因此我有两个包含大量行的文件: 文件1 71528 1452 14587 文件2 country_hoj_17458 9 CA 5 CA 78.4 country_hoj_1452 10 CA 15 CA 96.5 country_hoj_14787 19 CA 51 CA 12.4 country_hoj_15742 19 CA 51 CA 12.4 country_hoj_171528 19 CA 51
71528
1452
14587
文件2
country_hoj_17458 9 CA 5 CA 78.4
country_hoj_1452 10 CA 15 CA 96.5
country_hoj_14787 19 CA 51 CA 12.4
country_hoj_15742 19 CA 51 CA 12.4
country_hoj_171528 19 CA 51 CA 12.4
我想打印第一列中模式(编号)文件1与文件2匹配的行。我想要一个像这样的文件
country_hoj_1452 10 CA 15 CA 96.5
country_hoj_14787 19 CA 51 CA 12.4
我的剧本是这样的:
filename = numbers.txt
filename2 = data.txt
with open(filename) as f:
with open (filename2) as m:
for line in f:
if line in m:
print (m)
我需要在里面修好什么?谁能帮助我,支持我?非常感谢
filename = 'numbers.txt'
filename2 = 'data.txt'
with open(filename) as numberLines:
with open (filename2) as dataLines:
nL = numberLines.read().splitlines()
dL = dataLines.read().splitlines()
dataReadLines = [j for i in nL for j in dL if i in j]
#dataReadLines = [i for i in nL]
print (str(dataReadLines))
另一个答案是每个键与其各自的数据配对。我已经更改了您的输入,您可以使用下面的代码轻松理解
from collections import defaultdict
filename = 'numbers.txt'
filename2 = 'data.txt'
with open(filename) as numberLines:
with open (filename2) as dataLines:
nL = numberLines.read().splitlines()
dL = dataLines.read().splitlines()
defDList = defaultdict(list)
dataReadLines = [defDList[i].append(j) for i in nL for j in dL if i in j]
#dataReadLines = [i for i in nL]
print (defDList)
