How to print to the same line - If Statement within a For Loop

Question

Python 3 - I am using a for loop to print values from a dictionary. Some dictionaries within rawData have "RecurringCharges" as an empty list. I am checking to see if the list is empty and either populating with "0.0" if empty or the "Amount" if populated.

Creating the IF statement in my For Loop presents a new print statement and prints to a new line. I would like it to be one continuous line.

for each in rawData['ReservedInstancesOfferings']:
    print('PDX', ','
          , each['InstanceType'], ','
          , each['InstanceTenancy'], ','
          , each['ProductDescription'], ','
          , each['OfferingType'], ','
          , each['Duration'], ','
          , each['ReservedInstancesOfferingId'], ','
          , each['FixedPrice'], ',',
          )
    if not each['RecurringCharges']:
        print("0.0")
    else:
        print(each['RecurringCharges'][0].get('Amount'))

why don't you just do the check in RecurringCharges before the first print, and then include the result in a single print statement? — SuperStew, Dec 15 '17 at 20:51

If using Python 3, add to the end of each print statement a comma and then end="", such as:

 print(each['RecurringCharges'][0].get('Amount'), end="")

I found the answer shortly after posting: include the parameter end='' in the first print statement.

for each in rawData['ReservedInstancesOfferings']:
    print('PDX', ','
          , each['InstanceType'], ','
          , each['InstanceTenancy'], ','
          , each['ProductDescription'], ','
          , each['OfferingType'], ','
          , each['Duration'], ','
          , each['ReservedInstancesOfferingId'], ','
          , each['FixedPrice'], ',', end=''
          )
    if not each['RecurringCharges']:
        print("0.0")
    else:
        print(each['RecurringCharges'][0].get('Amount'))

Instead of using the print function, use stdout!

import sys
sys.stdout.write('this is on a line ')
sys.stdout.write('and this is on that same line!')

With sys.stdout.write(), if you want a newline, you put \n in the string, otherwise, it's on the same line.

Of course you could just follow How to print without newline or space?

but in that case, it would be better to insert your expression as the last argument in a ternary expression:

      , each['ReservedInstancesOfferingId'], ','
      , each['FixedPrice'], ','
      , "0.0" if not each['RecurringCharges'] else each['RecurringCharges'][0].get('Amount')
      )
