[英]Read 3rd line of file and then every
我有一個很大的文件,看起來像這樣:
Name: Block of line 1
Data: Block of line 2
**Important line 3**
Not important line 4
Not important line 5
**Another important line 6**
Not important line 7
Name: Block of line 1
Data: Block of line 2
**Important line 3**
Not important line 4
Not important line 5
**Another important line 6**
Not important line 7
Name: Block of line 1
Data: Block of line 2
**Important line 3**
Not important line 4
Not important line 5
**Another important line 6**
Not important line 7
在python中,我想讀取第3行和第6行, 或者當我使用.read()時,使其成為第2行和第5行
我的代碼只打印第一個塊,因此理想情況下,我想遍歷它:
files = open(fo, 'r')
for i, line in enumerate(files):
if i == 2:
print line
elif i == 5:
print line
break
files = open(fo, 'r')
for i, line in enumerate(files):
if i%8 == 2:
print line
elif i%8 == 5:
print line
那應該起作用,這需要i
mod 8,因為看起來每個塊長8行。 這不是最好的解決方案,您可能應該將數據保持整潔的格式。
甚至更簡單:
files = open(fo, 'r')
for i, line in enumerate(files):
if i%8 == 2 or i%8 == 5:
print line
