使用python打印unicode文本

Question

I have a dictionary that is filled with lists where the data was read from an excel file. All of the text is unicode however I do not have any special characters. I am trying to write the data that is located in the lists to a .txt file but I'm having trouble printing the lists out.

target.write("move % to 100 100") % product[1][0]
target.write("\n move % to 200 100") % product[1][1]
target.write("\n connect % to %") % (product[1][0], product[1][1])

product is the dictionary that holds the multiple lists. is there an easy way to format my .write statement so it can accept unicode. the error I'm getting is

"Type Error: unsupported operand type(s) for %: 'Nonetype' and 'unicode'

Answer 1

我只是个白痴，发现我可以键入强制转换产品，因此str（product [1] [0]）可以满足我的需求

Answer 2

The error is coming from the parameters to the format strings not being inside the write parentheses. target.write(...) returns None so you are effectively processing:

None % product[1][0]

Another problem '%' is not a string formatting command by itself. %s is probably what you want. If you are using Python 2.X your format strings are not Unicode. Add u in front of the strings.

Here's the fixes:

target.write(u"move %s to 100 100" % product[1][0])
target.write(u"\n move %s to 200 100" % product[1][1])
target.write(u"\n connect %s to %s" % (product[1][0], product[1][1]))

Or use the new .format method:

target.write(u"move {} to 100 100".format(product[1][0]))
target.write(u"\n move {} to 200 100".format(product[1][1]))
target.write(u"\n connect {} to {}".format(product[1][0], product[1][1]))
