python读取某行 python readline读取指定行

1 利用python的readlines()函数2113:

[python] view plain copy

fobj = open(r'Ori.Data.txt','r')
for line in fobj.readlines()[1000:]
fobj.close()

2 利用5261 linecache

[python] view plain copy

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

3 读取10行到13行中的内容4102

[python] view plain copy

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

4 求文本的行1653数

[python] view plain copy

fobj = open('Ori_Data.txt','r')
row_len = len(fobj.readlines()) 
[python] view plain copy

[python] view plain copy

fobj = open(filepath,'r')
data = fobj.read()
fobj.close()
text_len = data.count('\n')
