Question

我想将打印输出分配给某个字符串变量

print "Cell:", nei, "from the neighbour list of the Cell:",cell,"does not exist"

你可以请一下建议吗？

Answer 1

使用简单的字符串连接：

variable = "Cell: " + str(nei) + " from the neighbour list of the Cell: " + str(cell) + " does not exist"

或字符串格式：

variable = "Cell: {0} from the neighbour list of the Cell: {1} does not exist".format(nei, cell)

Answer 2

这不是Python的工作方式。如果您 NOT 有足够的理由，请尽量使用=。但如果你坚持，你可能会这样做。（同样，这是非常不必要的）

    def printf(*args):
        together = ''.join(map(str, args))    # avoid the arg is not str
        print together
        return together
    x = printf("Cell:", nei, "from the neighbour list of the Cell:",cell,"does not exist")

如果您只是尝试将事物加入字符串中，您可以采用多种方法：

x = ''.join(("Cell:", str(nei), "from the neighbour list of the Cell:",str(cell),"does not exist"))
x = "Cell:%s from the neighbour list of the Cell:%s"%(nei, cell)
x = "Cell:{} from the neighbour list of the Cell:{}".format(nei, cell)
x = "Cell:{key_nei} from the neighbour list of the Cell:{key_cell}".format({'key_nei':nei, 'key_cell':cell})
