Accessing nested dictionary contains list in python

I want only values from list inside nested dictionary.
Please advise whether I can print it directly rather than using a for loop.

dict_st={
  "students": [
    {
      "firstName": "Alex",
      "lastName": "Rodriguez"
    },
    {
      "firstName": "David",
      "lastName": "Crosby"
    },
    {
      "firstName": "Anna",
      "lastName": "Weston"
    }
  ]
}

for key, value in dict_st.items(): 
    for key1 in value:
        print ( key1["firstName"] )

OUTPUT:

Alex
David
Anna

I am looking for doing it one liner print statment something like below. Is this possible?

print ( dict_st["students"][0] )

OUTPUT:

{'firstName': 'Alex', 'lastName': 'Rodriguez'}

I am looking only "Alex" to be printed in single print statement.

>Solution :

It’s easy:

print ( dict_st["students"][0]["firstName"] )
