Split a paragraph of Chinese, split with Chinese commas, how to write?

python **: Directly call the built-in function split(str,',')

The number of parameters in split is an array, and there can be multiple acres of unique parameters, for example"Xun Zhi Pei,",n")

In a database system, a null value is (nothing).

Explanation: The so-called null is nothing, not even 0, 0 is the terminator in the string, but it occupies space in physical memory, equal to a byte, and null is not even this byte. In the database, it is strictly distinguished, any number is null when it is operated with null, and whether the value is equal to null can not be simply used =, but the is keyword.

Null (null).

The value indicates that the value is unknown (in practice, if null is used, it means that the value of the variable is unknown, for example, if the mobile phone number is set to null, it means that you do not know what the mobile phone number is). A null value is different from a blank or zero value. There are no two equal null values.

Comparing two null values or comparing null values to any other value returns unknown because each null value is unknown.

An empty string is also a deterministic value when writing data, so even if not null is defined, it can be written.

You're all commas, and as soon as the split hits the same, it starts to intercept, and in the end, all the matches are met, and of course it's empty. If you want to get a comma, then you should add spaces between several commas, and then split the spaces, of course, you will end up with a very depressed look.

Because yours is a series of commas.

1,2,3,4,5 split out is [.]"1","2","3","4","5"], you can imagine this, it must be all empty strings.

Because it puts","As a separator, if yes"1,2", which would result in an array subscript of 0 as :1 and a subscript of 1 as :2. You can see the API help documentation.

Because the comma is preceded and followed by empty characters, all times when converted to an array are an empty string array.

no why

Separated by a comma, it is intercepted, and the things on both sides of the comma, of course, are empty"a,fadasd,555", if separated by commas, you will get an array of strings.

It must be empty, and you don't have any characters between your commas.

For example:"12,123,1234";Split into three strings: 12, 123, and 1234.

Because of you, there's no data between them.

Your comma is an empty string.

Isn't that right? It's supposed to be an empty string.

The commas are all divided, you have no characters!

string str = "a+b+c";

string strs = "\\+");

for (int i = 0;i < i++) and that's it.

The split parameter is not a string, but a regex, which is a regular expression.

The sign has a special meaning in a regular expression (indicating one or more times), so your "+" is ""appears once or more times," "has no meaning and is not a space".

string strs="[+]");

string strs="\\+");

All of the above is true, I was just passing by, and I didn't mean to grab points! Don't give me points.

public static void getstr()

To escape the +...

If it's not correct, I'll give you my head! I've tested it! I hope to give points! Thank you! Hehe!

Go check the API.

split("") is a regular expression.

So just understand the representation of the regular expression "+".

public static void main(string args)}

Is it something you want?

Tell me how you want to divide it.

I'm sorry.

I won't. It's better to take 2 points.

In English, commas separate two complete sentences, and there should be words such as and between the two sentences, which is more casual in Chinese

Punctuation marks in English occupy one character"

Chinese punctuation marks it dots two characters ".

The comma in English is equivalent to the punctual in language.

I think you should look something like this, string s="coordinates 1,10,30,10|."Coordinates 2, 30, 30, 30|Coordinates 3, 50, 30, 50".

Step 1,'|0] for coordinates 1,10,30,10 step 2,'|0].split('The value of 0] is the number in coordinate 1, but the numbers in it are different, and they can be separated twice.

Split a set of coordinates The question is whether there is a carriage return at the end? It's better to send me the file and I'll debug it. Hi I'll put it.
