Getting all the branches in an area by just the area number?
Is there any way to get all the branches in an area inclduing from bus # and to bus# by just using the area number?

Yes, there is. Define a subsystem from the area(s) and use the subsystem data retrieval APIs. Something like the untested code below. This could potentially be cleaned up a bunch, but similar code has worked well enough for me in the past.
MySubsystem = 1 ## Arbitrary subsystem number, 0 through 11 are allowed I think?
MyAreas = [1,2,3,4]
ierr = psspy.bsysinit(MySubsystem)
ierr = psspy.bsysadd(MySubsystem, numarea=len(MyAreas), areas=MyAreas)
ierr, ckts = psspy.abrnchar(sid=MySubsystem, string='ID')
ierr, FromNum = psspy.abrnint(sid=MySubsystem, string='FROMNUMBER')
ierr, ToNum = psspy.abrnint(sid=MySubsystem, string='TONUMBER')
## PSSE returns a "list of lists" for each of the subsystem data retrieval functions
## We need to pull out the first element of each to make it easier to work with:
ckts = ckts[0]
FromNum = FromNum[0]
ToNum = ToNum[0]
BranchList = []
for i in range(len(ckts)):
BranchList.append([ckts[i], FromNum[i], ToNum[i]])

Comparing accc results from two different SAV files?
How do you output the load of the bus and store it as a variable
"insufficient access rights. FDNSD264 (FDNS_CLOS/CLSPTI)" error in PSSE
Extract Bus Voltage Magnitude and Angle from .sav case
Checking whether the voltage within the range
Is there anyway to create .con and .mon files with PSSPY?
Where can I put the Branch ID?
