[英]keyError on newline when format multi-lines string
print("xy{0}z".format(100))
xy100z
Let's try string with multi-lines. 让我们尝试使用多行字符串。
The string i want to format it. 我要格式化的字符串。
strs='''
.item{0}{
background-image:url("img/item{0}_1.jpg");
background-repeat: no-repeat;
background-position: 0px 0px;
}'''
>>> print(strs)
.item{0}{
background-image:url("img/item{0}_1.jpg");
background-repeat: no-repeat;
background-position: 0px 0px;
}
Now to format it with some number. 现在用一些数字格式化它。
print(strs.format(100))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
KeyError: '\n background-image'
You should replace {
with {{
/ }
with }}
to mean {
/ }
literally. 您应将
{
替换为{{
/ }
}}
来表示{
/ }
字面意思。
strs='''
.item{0}{{
background-image:url("img/item{0}_1.jpg");
background-repeat: no-repeat;
background-position: 0px 0px;
}}'''
print(strs.format(100))
prints: 打印:
.item100{
background-image:url("img/item100_1.jpg");
background-repeat: no-repeat;
background-position: 0px 0px;
}
