Aligning printed strings in Python

Question

print('The most frequent bigram tags are:\n')
bigram = bigram_frequency(lines)
for i in bigram:
    print(i[0]+"\t\t"+str(i[1]))

here's what I get:

N+N         5
N+DELM      3
DELM+DELM         2
N+P         2
DELM+P      2
P+N         2
DELM+N      2
CON+N       2
N+CON       2

How should I align that funny 2 from the third row with the rest of the group?

Youc can use format:

for i in [('fgd',1),('dg',2),('ggdd',3),( 'dd',4)]:
    print("{:5s} {:5d}".format(i[0], i[1]))


fgd       1
dg        2
ggdd      3
dd        4

You can use string formatting to get a specific text width, padded with spaces:

for tag, frequency in bigram:
    print('{tag:10} {frequency}'.format(tag=tag, frequency=frequency))

Change the 10 to the maximum width of the first column.
