Go语言中转换JSON数据简单例子

Go语言转换JSON数据真是非常的简单。以EasyUI的Demo为例,将/demo/datagrid/datagrid_data1.json 拷贝到$GOPATH/src目录: JSON.go: 代码如下: package main import ( “encoding/json” “fmt” “io/ioutil” ) type product struct { Productid string Productname string Unitcost float32 Statu

This error occurs when you try to assign a value to an item in a string, but strings in Python are immutable, meaning they cannot be changed once created. For example: ``` my_string = "hello" my_string[0] = "H" ``` The second line tries to change the first character of the string to "H", but this will result in the 'str' object does not support item assignment error. To modify a string, you need to create a new string with the desired changes. For example: ``` my_string = "hello" new_string = "H" + my_string[1:] print(new_string) # "Hello" ``` Here, we create a new string that starts with "H" and includes the rest of the characters from the original string using string slicing.
