python - SQLAlchemy and pylint -


sqlalchemy seems give me ton of errors on pylint can't resolve.

the first problem each table must defined new class.

example:

class person(base):     """person table definition"""     __tablename__ = 'person'     id = column(integer, primary_key=true)     name = column(string(30))

...causes these errors for each table define:

w: 20, 0: class has no __init__ method (no-init) r: 20, 0: few public methods (0/2) (too-few-public-methods)

the second problem using global variable sqlalchemy engine , base constructs. i'm not sure how can refactor code make these variables not global, since parameter base must passed table class definitions above.

base = sqlalchemy.ext.declarative.declarative_base() global engine ... def create_sqla_engine():     """create sqla engine"""     global engine     engine = create_engine('mysql+mysqlconnector://root:@127.0.0.1:3306/sqlalchemy_example')

i'm new python seems ugly. pylint complains it, too:

c: 51, 0: invalid constant name "engine" (invalid-name)

finally, pylint thinks i'm not using imports using in code.

w: 15, 0: unused declarative_base imported sqlalchemy.ext.declarative (unused-import) w: 16, 0: unused sessionmaker imported sqlalchemy.orm (unused-import)

...why? pylint not compatible python3? should importing modules need within methods used, instead of @ top of file?

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
