Python 3.x Python将字符串与具有转义字符的字符串变量连接起来
我有一个python脚本命令,如下所示:Python 3.x Python将字符串与具有转义字符的字符串变量连接起来,python-3.x,scripting,Python 3.x,Scripting,我有一个python脚本命令,如下所示: start_command = [ "load=" + location + "/lib/abc " + "conf=myconf " + location + "/bin/mysqld " "--defaults-file=" + location + "/var/myfile.cnf "
start_command = [
"load=" + location + "/lib/abc " + "conf=myconf " +
location + "/bin/mysqld "
"--defaults-file=" + location + "/var/myfile.cnf "
]
我想将代码的第二部分作为变量(connect_str)推送&在start命令中连接。但它不起作用。这是因为逃避角色吗
connect_str="conf=myconf " +
location + "/bin/mysqld "
"--defaults-file=" + location + "/var/myfile.cnf "
start_command = [
"load=" + location + "/lib/abc " + connect_str
我的错误是声明了我更改过的字符串变量&使其工作。这实际上是注释问题,因为放入了多行
connect_str="conf=myconf " + location + "/bin/mysqld " "--defaults-file=" + location + "/var/myfile.cnf "
start_command = [
"load=" + location + "/lib/abc " + connect_str
]
有没有更好的方法来解决这个问题,而不是把它放在一行中?我的错误是声明了我更改过的字符串变量并使它工作。这实际上是注释问题,因为放入了多行
connect_str="conf=myconf " + location + "/bin/mysqld " "--defaults-file=" + location + "/var/myfile.cnf "

"load=" + location + "/lib/abc " + connect_str
]
有没有更好的方法来解决这个问题,而不是把它放在一行中?如果你想连接str,它应该是str,我在你的代码中看到一个列表,在你的there are/中没有转义符this\这个。我建议您使用这样的格式更好
connect_str="conf=myconf {} /bin/mysqld --defaults-file={} /var/myfile.cnf ".format(location,location)

connect_str="conf=myconf {} /bin/mysqld --defaults-file={} /var/myfile.cnf ".format(location,location)
是,使用\进行scape\n
connect_str = "conf=myconf " + location + \
" /bin/mysqld " "--defaults-file=" + location + \
" /var/myfile.cnf "
