Cannot Figure out how String Substitution works in Python 3.x [closed]

Answer 1

Try sending the entire string with formatting to print.

print ('%.2f' % 6.42340)

Works with Python 3.2

In addition, the format works by providing an index to the provided agruments

print( "hello{0:.3f}".format( 3.43234 ))

Notice the '0' in front of the format flags.
