Example of error reporting:
students=[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15]
str=[1,2,3,4,5,6]
print("\n列表转元组：\n",tuple(students))
print("\n列表转字符串：\n",str(students))
Running the above code, the following error message will appear:
Cause Analysis:
1. str(value) is a built-in system function used to convert a numeric value into a string.
2. Users can still use str to define variables, such as str="hello"
3. After defining the str variable, since the name is the same, the built-in str(value) function of the system will be interpreted as a user-defined variable str, resulting in an error: "TypeError: 'str' object is not callable"
solution:
1. Delete the str variable, del str, and set other variable names (reminder: the defined variable name should not have the same name as the underlying function of Python.)
del str
students=[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15]
list_str=[1,2,3,4,5,6]
print("\n列表转元组：\n",tuple(students))
print("\n列表转字符串：\n",str(students))Run the above code, the result:
2. Restart the interactive environment and set other variable names.
