the reference answer GPT ᴼ ᴾ ᴱ ᴺ ᴬ ᴵ < br / > you can use string functions and insert a comma in the cycle to the given string. Here is an example code written in Python that inserts a comma between every two characters:
string = "31323531a102SgP"
new_string = ""
for i in range(0, len(string), 2):
new_string += string[i:i+2] + ","
# 移除最后一个逗号
new_string = new_string[:-1]
print(new_string)
This code divides the string into groups of two characters and inserts a comma between each group. The last comma needs to be removed after the loop ends. The output is:
31,32,35,31,a1,02,Sg,P
You can modify this code as needed, such as changing the group size or changing the separator.
Hope to adopt ha, thank you! 1, the solution is as follows
string newStr = string.Empty;
string str = "31323531a102SgP";
for (int i = 0; i < str.Length; i++)
{
if (i > 0 && i % 2 == 0)
{
newStr += ',';
}
newStr += str[i].ToString();
}
newStr = newStr.TrimEnd(','); // 把最后一个逗号移除

You can Insert commas between every two characters using the string insert method. The specific methods are as follows:
string str = "31323531a102SgP";
string result = string.Empty;
for (int i = 0; i < str.Length; i += 2)
{
result += str.Substring(i, 2) + ",";
}
// 去掉最后一个逗号
result = result.Remove(result.Length - 1);
Console.WriteLine(result);
A loop is used here, taking two characters at a time from the original string and concatenating them with a comma into a new string. Finally, we need to remove the last comma to get the final result. In this example, the final output is: 31,32,35,31,a1,02,Sg,P.
