从文件中读取行添加附加行

Question

This is the contents of my file ITEM.dat is

DB1:TEST1:Y

DB2:TEST2:N

Code is

MYFILE='/tmp/ITEM.dat'
M_ITMES=['TEST1'] 
for ITEM in ITMES:
if ITEM in open(MYFILE):
    if not line.startswith('#'):
        ITEM_YN=(line.split(':'))[2]
        print(ITEM_YN)

The print command results in additional blank line after Y

Y

This does not occur when I use

ITEM_YN=(line.split(':'))[1]

Answer 1

line includes the new line character as does the final item in line.split(':') . Since you likely want to use that item for other things, trim the newline before the split:

ITEM_YN = line.strip().split(':')[2]

Notice, I also got rid of those extra unneeded parens.
