Try-except with if conditions?

Question

I have created if-else statements within my functions to check if certain conditions are met. However, I need to convert it try-except statement since the app I am working on is set up so that when a condition is met, it creates log info statements and when it is not met it creates log error statements. Currently my code looks like:

if (conditon1 == 1):
    print('Everything is good')
else:
    orig_diff = list(set(sheetnames).difference(file.sheet_names))
    new_diff = list(set(file.sheet_names).difference(sheetnames))
    if len(orig_diff) != 0:
        print("{} cond1 not met".format(','.join(orig_diff)))
    if len(new_diff) != 0:
        print("{} cond2 not met".format(','.join(new_diff)))

I want it to be so that if the if-condition is met then it will print the info statement. But if it is not met, then the else statements will be executed. Something like:

try:
   return bool(condition1 == 1)
   print('Everything is good')
except:
   orig_diff = list(set(sheetnames).difference(file.sheet_names))
        new_diff = list(set(file.sheet_names).difference(sheetnames))
        if len(orig_diff) != 0:
            print("{} cond1 not met".format(','.join(orig_diff)))
        if len(new_diff) != 0:
            print("{} cond2 not met".format(','.join(new_diff)))

But, I can't seem to get this to work and even when the condition is not met it returns 'Everything is good'.

I think this would be a good way of doing it - if cond1 equals 1, it'll go down the happy path , the else block. If it doesn't (the assert ion fails, so the condition isn't met), it does what you wanted it to - prints an error message.

try:
   assert(condition1 == 1)
except AssertionError:
   orig_diff = list(set(sheetnames).difference(file.sheet_names))
        new_diff = list(set(file.sheet_names).difference(sheetnames))
        if len(orig_diff) != 0:
            print("{} cond1 not met".format(','.join(orig_diff)))
        if len(new_diff) != 0:
            print("{} cond2 not met".format(','.join(new_diff)))
else:
    print("Everything's fine!")
