当我试图将数据传递给另一个函数时，它向我显示了很多错误

Question

此代码成功运行..

import urllib.request
def profanity():
connection = urllib.request.urlopen('http://www.wdylike.appspot.com/?q='+'bal')
output = connection.read()
print(output)
connection.close()
profanity()

但是我想运行下面的代码给我带来了问题。但我想传递从本地txt文件中读取的数据并将此数据传递给profanity（）函数。该怎么办？

import urllib.request

def read_file():
    qoutes=open(r"C:\Python34\profanity.txt")
    a=qoutes.read()

    profanity(a)
    qoutes.close()

def profanity(b):
    connection = urllib.request.urlopen('http://www.wdylike.appspot.com/?q='+b)
    output = connection.read()
    print(output)
    connection.close()
##profanity()

read_file()
