Python What is difference between file iterator and list iterator? -


this question has answer here:

if have file iterator

with open('test1.txt','r') f1:  print(f1.__next__())

but if same thing list, doesn't work.

a1 = [1,2,3,4,5] a1.__next__()

so, difference between file iterator , list iterator? file , list (or tuple, dictionary, etc.) iterators behave differently?

there no such file iterator , list iterator.iterator works on iter objects. list iterable , not iter object, can make them iterable.

a =[1,2,3,4,5] a= iter(a) a.next()

all python data types except number can made iterable.

confused python lists: or not iterators?

java - sharing object across different classes -

i need "design" advise. have static jdbc objects , "main entry class" shared among other classes. my mainclass looks this: public static jdbc db1; public static jdbc db2; connectdb(makedirectconnection) // depending on runtime passed argument public static connectdb(boolean makedirectconnection) { if(makedirectconnection) // use direct connection db1 = jdbcfactory.getinstance("db/config/main/db1.properties"); db2 = jdbcfactory.getinstance("db/config/main/db2.properties"); } else { // connect using via ssh tunnel (different host , port) db1 = jdbcfactory.getinstance("db/config/tunnel/db1.properties"); db2 = jdbcfactory.getinstance("db/config/tunnel/db2.properties"); } jdbcfactory maintains map of instances. it kinda works ok, if want make unit test classes db1 or db2 being used null pointer exception if unit test don't mainclass.dbconnect() make thing worse - test classes need 1 more dif...
