我需要用python 2.7从.txt文件中读取数据表,并将其解析为变量先生... 我希望有人帮助我..
我有关于.txt(10项)的数据:
LEW01,14/01/2016,07:50:00,15.6,-19,943,-8.7,-228,-19,943,-8.7,-0.9,48.5,4.14,12.39 LEW01,14/01/2016,08:00:00,16.2,-18,944,-8.6,-229,-19,943,-8.6,-0.9,48.5,4.14,12.39 LEW01,14/01/2016,08:10:00,16.8,-19,943,-8.7,-228,-18,944,-8.6,-0.9,48.4,4.16,12.39 LEW01,14/01/2016,08:20:00,17.6,-18,944,-8.6,-229,-18,943,-8.6,-0.9,48.5,4.16,12.44 LEW01,14/01/2016,08:30:00,18.4,-19,943,-8.6,-229,-18,943,-8.6,-0.9,48.5,0.96,12.44 LEW01,14/01/2016,08:40:00,19.4,-18,944,-8.6,-230,-18,943,-8.6,-0.9,48.4,4.18,12.49 LEW01,14/01/2016,08:50:00,20.8,-19,943,-8.7,-230,-18,943,-8.6,-0.9,48.6,4.18,12.49 LEW01,14/01/2016,09:00:00,22.2,-18,944,-8.6,-231,-18,942,-8.6,-0.9,48.6,4.18,12.49 LEW01,14/01/2016,09:10:00,23.4,-19,943,-8.7,-232,-17,942,-8.6,-0.9,48.6,4.18,12.54 LEW01,14/01/2016,09:20:00,24.6,-18,944,-8.6,-233,-17,942,-8.6,-0.9,48.7,4.18,12.59
当我用代码python编译时:
with open('data_peng.txt') as x:
for rec in x:
a=rec.split(',')[0]
b=rec.split(',')[1]
c=rec.split(',')[2]
d=rec.split(',')[3]
e=rec.split(',')[4]
f=rec.split(',')[5]
g=rec.split(',')[6]
h=rec.split(',')[7]
i=rec.split(',')[8]
j=rec.split(',')[9]
k=rec.split(',')[10]
l=rec.split(',')[11]
m=rec.split(',')[12]
n=rec.split(',')[13]
o=rec.split(',')[14]
输出:
>>> a 'LEW01' >>> b '14/01/2016' >>> c '09:20:00' >>> d '24.6' >>> e '-18' >>> f '944' >>> g '-8.6' >>> h '-233' >>> i '-17' >>> j '942' >>> k '-8.6' >>> l '-0.9' >>> m '48.7' >>> n '4.18' >>> o '12.59'
我想要的,例如变量c:
>>> c [07:50:00,08:00:00,08:10:00,08:20:00,08:30:00,08:40:00,08:50:00,09:00:00,09:10:00,09:20:00]
请帮助我,非常感谢
答案 0 :(得分:1)
这是一个快速解决方案,它将使用您要查找的列名填充单个对象:
import csv
o = {}
cols = ['a','b','c','d','e','f','g','h','i','j','k','l','m','n','o']
with open('data_peng.txt', 'r') as csvin:
csvin = csv.reader(csvin)
for row in csvin:
for idx, col in enumerate(cols):
o.setdefault(col, []).append(row[idx])
print o['c']

怎么样:
with open('data_peng.txt') as x:
col3 = [line.split(',')[2] for line in x]
print(col3)
话虽如此,它看起来像一个CSV,任何更复杂的解析都可能受益于python的内置csv module的使用。
另外,我编辑了你问题的格式,请确保我没有改变任何重要的内容。
