Hi
I am fairly new to Python. I am writing some code that uses a dictionary to
store definitions of hardware registers. Here is a small part of it:
import sys
register = {
'address' : 0x3001c,
'fields' : {
'FieldA' : {
'range' : (31,20),
},
'FieldB' : {
'range' : (19,16),
},
},
'width' : 32
};
def main():
fields = register['fields']
for field, range_dir in fields: <== This line fails
range_dir = field['range']
x,y = range_dir['range']
print(x, y)
if __name__ == '__main__':
main()
I want the code to print the range of bits of each field defined in the
dictionary.
The output is:
Traceback (most recent call last):
File "testdir.py", line 32, in <module>
main()
File "testdir.py", line 26, in main
for field, range_dir in fields:
ValueError: too many values to unpack (expected 2)
Please will someone explain what I am doing wrong?
Also I would like to ask how I could print the ranges in the order they are
defined. Should I use a different dictionary class or could I add a field to
the dictionary/list to achieve this?
Best regards
David
