每当我尝试在Raspberry PI上运行此python脚本时,我都会遇到问题:
import socket
import sys
# Create a TCP/IP socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# Bind the socket to the port
server_address = ('localhost', 10000)
print >>sys.stderr, 'starting up on %s port %s' % server_address
sock.bind(server_address)
# Listen for incoming connections
sock.listen(1)
while True:
# Wait for a connection
print >>sys.stderr, 'waiting for a connection'
connection, client_address = sock.accept()
try:
print >>sys.stderr, 'connection from', client_address
# Receive the data in small chunks and retransmit it
while True:
data = connection.recv(16)
print >>sys.stderr, 'received "%s"' % data
if data:
print >>sys.stderr, 'sending data back to the client'
connection.sendall(data)
else:
print >>sys.stderr, 'no more data from', client_address
break
finally:
# Clean up the connection
connection.close()
我收到此错误:
File "server.py", line 20
try:
^
IndentationError: unexpected indent
你能告诉我这里有什么问题吗?该脚本应该创建一个简单的TCP / IP服务器,我对客户端没有这样的问题,所以我真的不明白我的错误在哪里...
答案 0 :(得分:3)
Python使用空格表示块的一个令人遗憾的副作用是,有时你会得到在整个源代码中混合了标签和空格的脚本。
由于此脚本非常小,您可以尝试删除每行代码前面的空格,然后重新加入它。
