如何解決Python的語法無效三重引號「」」

Question

我對codegen.py遇到一個錯誤嘗試使用make來構建RabbitMQ的服務器時，我使用的是64位的Windows 7，Python33，erl5.10.3，Cygwin和GNU 。讓4.0的i686-PC-cygwin的，我讀了三引號在Python接受我如何解決這個問題

D:\cygwin\bin\make 
Makefile:378: deps.mk: No such file or directory 
python codegen.py body ../rabbitmq-codegen//amqp-rabbitmq-0.9.1.json ../rabbitmq 
-codegen//credit_extension.json src/rabbit_framing_amqp_0_9_1.erl 
    File "codegen.py", line 110 
    %%""" 
     ^
SyntaxError: invalid syntax 
Makefile:144: recipe for target 'src/rabbit_framing_amqp_0_9_1.erl' failed 
make: *** [src/rabbit_framing_amqp_0_9_1.erl] Error 1 

codegen.py直到錯誤出現（代碼最後一行）：

問題不在於三重引號。因爲你使用Python 3，print是一個函數，而不是聲明。環繞在括號中的三重引號的字符串。
