A quoted string can be embedded in an argument. 3) A double quotation mark preceded by a backslash is interpreted as a literal double quotation mark. 4) Backslashes are interpreted literally, unless they immediately precede a double quotation mark. 5) If backslashes immediately precede a double quotation mark, every pair of backslashes is interpreted as a literal backslash. If the number of backslashes is odd, the last backslash escapes the next double quotation mark as described in rule 3. t s t"s\is\"t(tFalseROtlentextendtjoin(tseqtresultt needquotetargtbs_buftc((s /usr/lib/python2.7/subprocess.pyt list2cmdlines4       cBseZdZeZdd!d!d!d!d!eed!d!ed!dd ZdZej dZ d!dZ dZ e rdZdZd Zd Zd!ejejejd Zd Zd ZdZdZdZeZndZedZdZdZ e!r)e!j"Z#nde$fdYZ%e%Z#dZe&j'e&j(e&j)e&j*e&j+e&j,dZ-d!e&j.e&j/e&j0e1j2dZdZdZdZ3dZ4dZdZd ZRS("s Execute a child program in a new process.
