Check the connection:

print (FTPError).center(80)
time.sleep(5)
It sends this error

the error message should be clear, you can't use +operator to sum a string and a dictionary, maybe you want to convert the dict to a string. If getFTPConfig('Pass') is returning a dictionary then
错误信息应该很清楚，您不能使用+运算符对字符串和字典求和，也许您想将 dict 转换为字符串。如果 getFTPConfig('Pass') 返回一个字典，那么
str(getFTPConfig('Pass'))+"whatever"

web_response = {2L: 67.0, 3L: 13.67, 4L: 10.25, 5L: 11.8, 6L: 11.83}
I've a dictionary named "web_response",For concatenation of dictionary with stringI used comma","
我有一本名为“web_response”的字典，为了将字典与字符串连接起来，我使用了逗号“，”
print "web_response=", web_response
Output:
输出：
web_response= {2L: 67.0, 3L: 13.67, 4L: 10.25, 5L: 11.8, 6L: 11.83}
