[英]Printing List as string in python
我是python的新手,如果找到打印行,則希望搜索字符串文件,並希望將輸出打印為
"mapp1=2"
"map2=6"
"MAP3"
樣例代碼:
import os
fname = "xx.txt"
new_list=[]
f=open(fname,'r')
for line in f :
key = line.strip().split('\n')
matching = [s for s in key if ("mapping" or "MAP") in s]
if matching:
if not line.startswith("#"):
new_list.append((key))
print new_list
values = ','.join(str(i) for i in new_list)
print values
failed_res = ','.join(str(j) for j in values)
print failed_res
此代碼的輸出是:
[mapp1=2],[map2=6],[MAP]
請給點建議
嘗試更換
','.join(str(i) for i in new_list)
通過
'\n'.join(str(i).replace('[', '"').replace(']', '"') for i in new_list)
輸出:
"mapp1=2"
"map2=6"
"MAP"
另外,不要忘記在腳本結尾處使用f.close()
