I wish to achieve this sort of output with string formatting:
GBP......0.8639......0.8399
I have tried using the following code (i stands for currency and e[0] and e[1] are buy and sell values):
"{i:.<10}{e[0]:.^6}{e[1]:.>6}".format(i=i, e=e)
but the above code does not align the second number to the right, but it just adds it behind the first number, like this:
GBP.......0.86390.8399
How can I correct this?
As a generalized solution:
Use this format string if you want the right column, center and left column to be aligned right, center and left respectively:
>>> '{0:.<10}{1:.^10}{2:.>10}'.format('GBP', 0.8639, 0.8399)
'GBP.........0.8639......0.8399'
# Another example
>>> '{0:.<10}{1:.^10}{2:.>10}'.format('GBPTEST', 0.90, 0.8)
'GBPTEST......0.9...........0.8'
OR, this format string if you want all the columns except rightmost column to be aligned right:
>>> '{0:.<10}{1:.>10}{2:.>10}'.format('GBP', 0.8639, 0.8399)
'GBP...........0.8639....0.8399'
# Another example
>>> '{0:.<10}{1:.>10}{2:.>10}'.format('GBPTEST', 0.90, 0.8)
'GBPTEST..........0.9.......0.8'
OR, this format string if you want all the columns to be aligned left:
>>> '{0:.<10}{1:.<10}{2:<10}'.format('GBP', 0.8639, 0.8399)
'GBP.......0.8639....0.8399 '
# Another example
>>> '{0:.<10}{1:.<10}{2:<10}'.format('GBPTEST', 0.90, 0.8)
'GBPTEST...0.9.......0.8 '
Change the value of 10 for each param based on the size of column you need.
Below will be the format string specific for the kind of params as mentioned in the question:
>>> '{i:.<10}{e[0]:.^10}{e[1]:.>10}'.format(i='GBP', e=(0.8639, 0.8399))
'GBP.........0.8639......0.8399'
# Another example
>>> '{i:.<10}{e[0]:.^10}{e[1]:.>10}'.format(i='GBPTEST', e=(0.90, 0.8))
'GBPTEST......0.9...........0.8'
Increase the last number from 6 to 12.
"{i:.<10}{e[0]:.^6}{e[1]:.>12}".format(i=i, e=e)
This gives you
GBP.......0.8639......0.8399
Your last two format specs only have a width of 6 and the values themselves are six digits, so there aren't any fill characters. If you want e[0] centered between i and e[1] with six dots on either side, construct the second format spec based on the length of e[0] - and don't specify a width for the other two.
>>> i = 'GPB'
>>> e = (0.8639, 0.8399)
>>> n = len(str(e[0]))
>>> s = '{i:}{e[0]:.^' + str(12+n) + '}{e[1]:}'
>>> s
'{i:}{e[0]:.^18}{e[1]:}'
>>> s.format(i = i, e = e)
'GPB......0.8639......0.8399'
>>>
or
>>> i = 'GPB'
>>> e = (0.8639, 0.8399)
>>> s1 = '{{i:}}{{e[0]:.^{n:}}}{{e[1]:}}'
>>> n = len(str(e[0])) + 12
>>> s = s1.format(n=n)
>>> s
'{i:}{e[0]:.^18}{e[1]:}'
>>> s.format(i = i, e = e)
'GPB......0.8639......0.8399'
>>>
