python parse variable inside print or varibale
===

trying to parse variable inside print statement.

    client = fabric.operations.prompt("Enter client's email address:")
    cmd = 'mysql -u %s -p%s -e "UPDATE users SET email = ' %(env.user, dbpasswd) + '"%client"' + ' WHERE id = 1" %s' %account
    print cmd

result:

    mysql -u root -password -e "UPDATE users SET email = %client WHERE id = 1" demo

desired result:

    mysql -u root -password -e "UPDATE users SET email = 'abc@xyz.com' WHERE id = 1" demo

thanks in advance.
