What is the use of “”“…”“” in python instead of “…” or '…', especially in MySQLdb cursor.execute

Question

is there a difference if i use """..""" in the sql of cusror.execute. Even if there is any slight difference please tell

Answer 1

It's used to split the query over many lines to format it nicely:

db.query("""
    SELECT *
    FROM employee, department 
    WHERE employee.DepartmentID = department.DepartmentID;
""")

Also using """...""" around a string allows you to not escape " and ' inside that string.

Answer 2

不可以，除了字符串可以包含换行符。
