Lo esperaba?
No sabía si iban a venir, pero lo esperaba .
I didn't know if they were going to come, but I hoped so.
Can someone explain why there is a "lo" in this sentence?
Do spanish speakers say "I hoped it so"?
Also in spanish in this sentence for example, "No sabía" means "I didn't know"( in a book I studying), does one automatically assume that it's the 1st person sing. that is being talked about here until otherwise informed Because I know in the imperfect tense 1st, 2nd, & 3rd person sing. all have the same ending except for ir,ser,ver.

"I didn´t know if they were going to come, but I hoped it." I´m not sure I see your angle, don´t you ever say that in English?
As for no sabía, it will be clear from context who´s being spoken of. If it´s not, the speaker will put in a pronoun for clarification. For example when we say "my eyes hurt, the movie was dark" it´s clear from context, but the other person is still allowed to say "you mean the lighting´s bad in the cinema, or it was so disturbing you forgot to blink?"
It just means "it", as you suspected.
I didn't know if they were going to come, but I hoped for it/expected it.
You can't always translate word-for-word if you want it to sound idiomatic. Your translation is smoother.
