我有这个数据文件,我必须找到它包含的3个最大数字
24.7 25.7 30.6 47.5 62.9 68.5 73.7 67.9 61.1 48.5 39.6 20.0
16.1 19.1 24.2 45.4 61.3 66.5 72.1 68.4 60.2 50.9 37.4 31.1
10.4 21.6 37.4 44.7 53.2 68.0 73.7 68.2 60.7 50.2 37.2 24.6
21.5 14.7 35.0 48.3 54.0 68.2 69.6 65.7 60.8 49.1 33.2 26.0
19.1 20.6 40.2 50.0 55.3 67.7 70.7 70.3 60.6 50.7 35.8 20.7
14.0 24.1 29.4 46.6 58.6 62.2 72.1 71.7 61.9 47.6 34.2 20.4
8.4 19.0 31.4 48.7 61.6 68.1 72.2 …所以我有文件:data2.txt
Lollypop,
Lolly pop,
ooh
lolly,
lolly, lolly;
lollypop, lollypop,
ooh lolly, lolly, lolly,
lollypop!
ba dum dum dum ...
LOL :-)
我需要循环遍历每行data2.txt只打印包含字符串'lol'的行并将输出打印到newfile
with open("data3.txt") as g:
with open("data2.txt") as lfp:
for lin in lfp:
if 'lol' in lin:
g.write(str(lin))
elif 'LOL' in lin:
g.write(str(lin))
elif 'Lol' in lin:
g.write(str(lin))
但我一直在收到错误:
g.write(str(lin))
io.UnsupportedOperation: not writable
