python 3.5 printing formated float number

Question

I've found something interesting with my python3.5

So this is the code

previous = 0.1234567891011121314
now = 2.98764627181

print("Before: {0:.15f}".format(float(previous)))
print("Now: {0:.15f}".format(float(now)))


print(" Before:{0:.15f} Now:{0:.15f} ".format(float(previous), float(now)))

and this is the result

Before: 0.123456789101112
Now: 2.987646271810000
Before:0.123456789101112 Now:0.123456789101112

So when I want to print them with one single print and format function python3.5 seems to not able to handle it. Am I doing something wrong?

Please provide the error or traceback you get that you would like us to help you fix. — match

The 0 in the {0:.15f} replacement field is a field name, as specified in the Python documentation for string formatting. When the field name is a number, it identifies a positional argument. Since you have 0 in both replacement fields, both are replaced with the positional argument numbered 0.

To use the other argument, use {1:.15f}.
