如何改变Python字典？

Python字典换行的方法如下：

1、换行时保证行尾逗号。

a={"key0":"val0",
"key1":"val1",
"key2":"val2"}

2、这种写法也允许长度不影响阅读:

a={"key0":"val0","key1":"val1",
"key2":"val2","key3":"val3",
"key4":"val4","key5":"val5"}

请注意，在这种情况下，每行的第一个非空白字符应与第一行括号后的字符对齐，最后的括号不会改变（直接跟随最后一个元素）。

3、另一种换行方式如下：

a={
"key0":"val0",
"key1":"val1",
"key2":"val2"
}
a={
"key0":"val0",
"key1":"val1",
"key2":"val2"
}

或是

a={
"key0":"val0","key1":"val1",
"key2":"val2","key3":"val3",
"key4":"val4","key5":"val5"
}
a={
"key0":"val0","key1":"val1",
"key2":"val2","key3":"val3",
"key4":"val4","key5":"val5"
}

在这种情况下，内容的每一行都需要比第一行多缩进一层(即四个空间)
