1-6、散列(hash) 1)、由逗号分隔的键/值列表,由{}大括号限定,键和值之间用冒号分隔,如:{"key1":valu1,"key2":"character string"...} 2)、键和值都是表达式,但是键必须是字符串。 2、获取变量: 2-1、顶层变量:${变量名} 变量名只能是字母、数字、下划线、$、#、@ 的组合,且不能以数字开头。
s="string"s1=s[:len(s)//2]s2=s[len(s)//2:]print(s1,s2) Output: str ing In the above code, we were dealing with a string containing an even number of characters. Thelen()function here is used to return the length of the string. We split the string into one half containing th...
separator && hasUnicode(string)) { return castSlice(stringToArray(string), 0, limit) } } return string.split(separator, limit) } 首先,对传入的limit进行了校验,如果没有传,那么就把分解的字符全部保留下来,如果传了,那么使用 使limit进行有意义的转化(如非负,不能有小数),如果limit没有意义则返回空...
The following code demonstrates a shard split operation that redistributes the hash keys evenly between each of the child shards, essentially splitting the parent shard in half. This is just one possible way of dividing the parent shard. You could, for example, split the shard so that the lowe...
