Accessing keys when loading from JSON - json

Question

I am new to Python and I can not seem to find a solution that I understand.
• When I load in the JSON file I can print out the list as a whole; but if I try to access the key I get KeyError.
• Am I right in saying that Python converts the JSON file into a Python dictionary?
• Also, how would I go about accessing keys and then checking against them?
Main Code:
JSON File:

Welcome to Stackoverflow Community.
JSON you have:
{
"credentials": [
{
"username": "Admin",
"password": "Password"
}
]
}
When Converted to the dictionary:
{'credentials': [{'username': 'Admin', 'password': 'Password'}]}
Understanding the output of credentials:
print(data["credentials"])
# Output:
[{'username': 'Admin', 'password': 'Password'}]
# Do observe that the output is in a list format.
# For better understanding let's assume there is more than 1 credential:
[
{'username': 'Admin', 'password': 'Password'}, # 0 of list
{'username': 'Admin1', 'password': 'Password1'} # 1 of list
]
Understanding the mistake:
# Instead of
data["username"]
# do
data["credentials"][0]["username"]
The Right way:
for i in len(data["credentials"]):
print("The username is ", data["credentials"][i]["username"])
Also, I encourage you to go through Python Tutorials before working on something.
Python is widely considered among the easiest programming languages for beginners to learn.
