unicode格式错误

Question

所以，我刚开始使用它的python twitter api挖掘twitter数据。 ，并且即将绘制鸣叫stucture 但我收到此错误

f.write('strict digraph {\n%s\n}' % (';\n'.join(dot),)) 
    UnicodeEncodeError: 'ascii' codec can't encode character u'\u201c' in position 108: 
    ordinal not in range(128) 

这是代码..

def draw_tweet_graph(g): 
OUT = "graph.dot" 
try: 
    nx.drawing.write_dot(g, OUT) 
except ImportError, e: 

    dot = ['"%s" -> "%s" [tweet_id=%s]' % (n1, n2, g[n1][n2]['tweet_id']) \ 
     for n1, n2 in g.edges()] 
    f = open(OUT, 'w') 
    f.write('strict digraph {\n%s\n}' % (';\n'.join(dot),)) 
    f.close()

你想codecs.open()为您的文件。
