clean-css-cli Format media print code with clean-css-cli - clean-css

Question

1. program with python excute clancss cli
I set level 2 and mergeMedia:off and the result is not well for me.
try:
#cmd = "cleancss -02 mergeMedia:off --compatibility ie8 -o {0} {1} ".format(dstFile, srcFile)
cmd = "cleancss -O2 mergeMedia:off;removeDuplicateMediaBlocks:off -o {0} {1} ".format(dstFile, srcFile)
os.system(cmd)
print("cleancss - {} - ok !".format(srcFile))
#os.remove(srcFile)
#os.rename(dstFile, srcFile)
except NameError as e:
print(e)
2. css source code
The style code like below.The first item "table" will be remove(see setp 3)
#media print {
table {
border: 1px solid black;
border-collapse: collapse;
table-layout: fixed;
}
table th {
border: 1px solid black;
}
table td {
border: 1px solid black;
}
.pageBreak {
page-break-after: always;
}
.noPrint {
display: none;
}
.borderable {
border: 2px solid black;
padding: 3px;
}
nav, aside {
display: none;
}
table.posprint {
border: 1px solid white;
border-collapse: collapse;
table-layout: fixed;
}
table.posprint th {
border: 1px solid white;
}
table.posprint td {
border: 1px solid white;
}
}
3. clean css output
The output of above setp 2 .
The first element was be removed and less brackets in the end .
#media print{border-collapse:collapse;table-layout:fixed}table td,table th{border:1px solid #000}.pageBreak{page-break-after:always}.noPrint{display:none}.borderable{border:2px solid #000;padding:3px}aside,nav{display:none}table.posprint{border:1px solid #fff;border-collapse:collapse;table-layout:fixed}table.posprint td,table.posprint th{border:1px solid #fff}
How can i change my program code and get the right output.
