如何用python读取txt文件里指定行的内容，并导入excel?

lnum = 0
with open('pit.txt', 'r') as fd:
    for line in fd:
        lnum += 1;
        if (lnum >= 10) && (lnum <= 13):
            print line
    fd.close()

------解决方案--------------------

Python code

def eachlineof(filename):
    ''' 逐行读取给定的文本文件，返回行号、剔除末尾空字符的行内容 '''
    with open(filename) as handle:
        for lno, line in enumerate(handle):
            yield lno+1, line.strip()

------解决方案--------------------

Python code

import linecache
print(linecache.getline(r'D:\z.txt',10))

------解决方案--------------------

如果文件不大，建议使用下面的方法。由于linecache会缓存，所以对大文件可以使用自己简单是实现getline如下：

Python code

def getline(thefilepath, desired_line_number):
    if desired_line_number < 1: return ''
    for current_line_number, line in enumerate(open(thefilepath, 'rU')):
        if current_line_number == desired_line_number - 1 : return line
    return ''
