Python讀取多個txt檔案並進行儲存

記憶力不好的孩紙得勤做筆記！

最近開始接觸python，現在分享下寫的第二個**，好了，多的不說，直接上**！作業系統為windons.

#coding:utf-8

import matplotlib.pyplot as plt
import numpy as np
#距離temp = 3.0
#定義字典相當於c++中巨集
for i in range(1,16):
path = 
#讀第乙個檔案
x = 
y = 
f = open(path["path1"])
line = f.readline()
while line:
#print line,
a,b = line.split()
line = f.readline()
#print line 
f.close()
#string to double
x = [ int( x ) for x in x if x ] 
y = [ float( y ) for y in y if y ] 
#find the maxdefinition
maxdef = np.max(y)
index = np.where(y == maxdef)
id = x[index[0]]
print maxdef
#print index
print id
#讀另外兩個檔案
u = 
v = 
w = 
f1 = open(path["path2"])
line1 = f1.readline()
while line1:
#print line,
c,d,e = line1.split()
line1 = f1.readline()
#print line 
f1.close()
#string to double
u = [ int( u ) for u in u if u ] 
v = [ int( v ) for v in v if v ] 
w = [ int( w ) for w in w if w ] 
#index1 = np.where(w == id)
print u[id]
print v[id] 
#write data
f2 = open(path["path3"], 'a')
f2.write(str(u[id]) + ' ' + str(v[id]) + ' ' + str(temp) + '\n')
f2.close()
temp += 0.5

打完收工！！！簡單的實現了對多個文字檔案的讀寫操作~
