So I have a text file for example:

```
RootObject: Sun

Object: Sun
Satellites: Mercury,Venus,Earth,Mars,Jupiter,Saturn,Uranus,Neptune,Ceres,Pluto,Haumea,Makemake,Eris
Radius: 20890260
Orbital Radius: 0

Object: Earth
Orbital Radius: 77098290
Period: 365.256363004
Radius: 6371000.0
Satellites: Moon

Object: Moon
Orbital Radius: 18128500
Radius: 1737000.10
Period: 27.321582

```

and I'm trying to input it into a dictionary. This is what I have so far but I keep getting an error...

```
#d = dictionary
#new_d = new dictionary

file = open("data.txt","r")
d = {}
def data(file):
    for line in file:
        if line != line.strip:
            continue
        line = line.strip()
        key = line.split(":")
        val = line.split(":")
        if key in d and key == "Object":
            print(d)
        d[key] = val
    print(d)

new_d = {}
with file as x:
    for d in data(x):
        new_d[d["Object"]] = d
print(nd)

```

I should be getting something like this:

```
{' Earth': {'Satellites': ' Moon', 'Orbital Radius': ' 77098290', 'Object': ' Earth', 'Radius': ' 6371000.0', 'Period': ' 365.256363004'}, ' Moon': {'Orbital Radius': ' 18128500', 'Object': ' Moon', 'Radius': ' 1737000.10', 'Period': ' 27.321582'}, ' Sun': {'Satellites': ' Mercury,Venus,Earth,Mars,Jupiter,Saturn,Uranus,Neptune,Ceres,Pluto,Haumea,Makemake,Eris', 'Orbital Radius': ' 0', 'Object': ' Sun', 'Radius': ' 20890260', 'RootObject': ' Sun'}}

```

I get this error:

```
Traceback (most recent call last):
  File "planet2.py", line 21, in <module>
    for d in data(x):
