Issue

This Content is from Stack Overflow. Question asked by TUSK ACT 4

i want to run this code

listf = [
    {"name":"akram"}
]
for i in listf:
    print(listf["name"])

and this error happened:

line 5, in <module>
    print(listf["name"])
TypeError: list indices must be integers or slices, not str

but in another code from another user :

students = [
    {"name": "Hermione", "house": "Gryffindor", "patronus": "Otter"},
    {"name": "Harry", "house": "Gryffindor", "patronus": "Stag"},
    {"name": "Ron", "house": "Gryffindor", "patronus": "Jack Russell terrier"},
    {"name": "Draco", "house": "Slytherin", "patronus": None},
]

for student in students:
    print(student["name"], student["house"], student["patronus"], sep=", ")

and it run normal

Solution

If you take a look at the second example they accessed students dictionaries via student not students. Let me show it to you differently:

for st in students: # Here I changed student by st
    print(st["name"], st["house"], st["patronus"], sep=", ")

Try this will help you make the distinction in your code:

listf = [
    {"name":"akram"}
]
for i in listf:
    print(i)

Output:

{"name":"akram"}

See? Here i is the dictionary. Here’s how you should access it:

listf = [
    {"name":"akram"}
]
for i in listf:
    print(i["name"])
