现在,我只是想用一个带有’|’的csv样式格式来获取它用于分隔数据项的符号,然后手动将数据提取到excel:

tmp = open('tmp.txt','w')
tmp.write(text)
tmp.close()

data1 = []

for line in open('tmp.txt'):
    line = line.lower()
    if 'SALARY' in line:
        line = line.replace(' ','|')
    line = line.replace('--', '')
    line = line.replace('- -', '')
    line = line.replace('-  -', '')
    line = line.replace('(1)', '')
    line = line.replace('(2)', '')
    line = line.replace('(3)', '')
    line = line.replace('(4)', '')
    line = line.replace('(5)', '')
    line = line.replace('(6)', '')
    line = line.replace('(7)', '')
    line = line.replace('(8)', '')
    line = line.replace('(9)', '')
    line = line.replace('(10)', '')
    line = line.replace('(11)', '')
    line = line.replace('(S)', '')
    line = line.replace('($)', '')
    line = line.replace('(#)', '')
    line = line.replace('$', '')
    line = line.replace('-0-', '0')
    line = line.replace(')', '|')
    line = line.replace('(', '|-')
    line = re.sub(r'\s(\d)', '|\\1', line)
    line = line.replace(' ', '')
    line = line.replace('||', '|')
    data1.append(line)
data = ''.join(data1)

问题是我必须做成千上万次,并且需要永远地通过每个表并保存我需要的项目.有没有办法创建一个字典,可以跟踪最左边列中列出的每个人的年份,工资,奖金,其他年度报酬等内容?

解决方法:

以下是一些可以帮助您入门的代码:

text = """JOHN ...""" # text without the header

# These can be inferred if necessary
cols = [0, 24, 29, 39, 43, 52, 71, 84, 95, 109, 117]

db = []
row = []
for line in text.strip().split("\n"):
    data = [line[cols[i]:cols[i+1]] for i in xrange((len(cols)-1))]
    if data[0][0] != " ":
        if row:
            db.append(row)
        row = map(lambda x: [x], data)
    else:
        for i, c in enumerate(data):
            row[i].append(c)
print db

这将生成一个包含每人元素的数组.每个元素都是所有列的数组,并且将包含所有行的数组.通过这种方式,您可以轻松访问不同年份,或者执行诸如连接人员标题之类的操作:

for person in db:
    print "Name:", person[0][0]
    print " ".join(s.strip() for s in person[0][1:])
    print

将产量:

Name: JOHN W. WOODS
