Both translate "esperar" but with different certainty: "hope" is an uncertain wish; "expect" is a near-certain anticipation.
To wish for something to happen, without being certain it will. There is uncertainty.

Espero que no llueva manana. Planeamos un picnic.

Ella espera obtener el ascenso, pero aun no esta segura.
We hoped the situation would improve, but it only got worse.
Esperabamos que la situacion mejorara, pero solo empeoro.
To anticipate something considered likely or that you have a right to receive. There is certainty or entitlement.
I expect you to be on time. This is a professional environment.
Espero que llegues a tiempo. Este es un ambiente profesional.
She is expecting a baby in March. Everyone is very excited.
Ella espera un bebe en marzo. Todos estan muy emocionados.

Common mistake
The classic Spanish-speaker error: "I expect it does not rain" (when you want to say you wish it would not rain). "Expect" implies you think something will happen, not that you desire it. "I hope it does not rain" is correct. The reverse: "I hope you to be on time" is incorrect — you cannot say "hope + person + infinitive". The "expect" structure is "expect + person + to + infinitive": "I expect you to be on time."
Trick to remember it
Certainty question: are you almost certain it will happen? "Expect". Do you just wish for it without certainty? "Hope". Key grammar structure: "I hope (that) + clause" (I hope it works). "I expect + person + to + infinitive" (I expect you to call). Do not mix them: "I hope you to call" does not exist in English.
Quick rule
Hope = uncertain wish (hopefully). Expect = near-certain anticipation (I am counting on it).
Did you know?
"I hope so" and "I expect so" are common replies but with very different nuances. "Do you think she will come?" / "I hope so" (I wish she would) vs "I expect so" (I think she probably will). In real conversation, choosing the wrong word can give a completely different impression of your confidence level.
