print ('%0.2f'+ % userUSD + '= %0.2f' + %Euro + 'Euro')
I'm using python 3.3 and while making a very simple currency converter I've stumbled upon this syntax error. Could you guys tell me how could I fix this and write the right way to print the floating point number in this case?
The syntax error is because you're using both the + and % operators in a row. When you use % for string formatting, you don't want + in between the format string and its arguments.
So, the most basic fix would be to get rid of the extra + characters:
print ('%0.2f' % userUSD + '= %0.2f' % Euro + 'Euro')
However, it would probably make more sense to combine the format strings together, and do just one formatting operation:
print('%0.2f = %0.2f Euro' % (userUSD, Euro))
In new code though it's generally recommended to use the more capable str.format formatting system, rather than the % operator:
print('{:.2f} = {:.2f} Euro'.format(userUSD, Euro))
This is the proper way to write Python 3 formatted strings, using str.format():
print("{:0.2f} = {:0.2f} Euro".format(userUSD, Euro))
This breaks down to taking each positional value and formatting it with two decimal places, just like you would with % above.
print ('%0.2f USD = %0.2f Euro' % (USD, Euro))
The formatted string comes inside a single pair of quotations. The variables come then as a list after a % symbol.
