具有字符串连接和延续的 Python str.format

Question

我想指定一个包含行继续符和连接符的字符串。如果我要回应一堆相关值，这真的很有用。这是一个只有两个参数的简单示例:

temp = "here is\n"\
    +"\t{}\n"\
    +"\t{}".format("foo","bar")
print(temp)

这是我得到的:

here is
    {}
    foo

这是我所期望的:

here is
    foo
    bar

什么给了？

Answer 1

你可以尝试这样的事情:

temp = ("here is\n"
        "\t{}\n"
        "\t{}".format("foo","bar"))
print(temp)

或者喜欢:

# the \t have been replaced with
# 4 spaces just as an example
temp = '''here is
    {}
    {}'''.format

print(temp('foo', 'bar'))

对比你有什么:

a = "here is\n"
b = "\t{}\n"
c = "\t{}".format("foo","bar")
print( a + b + c)
