Print a list of tuples as table

Using Format Specification Mini-Language

print "HEADER1       HEADER2    HEADER3"
for ele1,ele2,ele3 in l:
    print "{:<14}{:<11}{}".format(ele1,ele2,ele3)

HEADER1       HEADER2    HEADER3
element1      element2   element3
elementelel4  element5   elementelement6
el7           el8        elel9

You can use ljust for left-aligning the element within a fixed width

column_width=20
for row in list:             
    for el in row:         
        print el.ljust(column_width), 
    print

output

element1             element2             element3            
elementelel4         element5             elementelement6     
el7                  el8                  elel9  

Assume that, all tuples in the list is of the same length, you can use this:

l = [('element1', 'element2', 'element3'), ('elementelel4', 'element5', 'elementelement6'), ('el7', 'el8', 'elel9')]
width = max(len(e) for t in l for e in t[:-1]) + 1 
format=('%%-%ds' % width) * len(l[0])
print '\n'.join(format % tuple(t) for t in l)

Output:

element1     element2     element3
elementelel4 element5     elementelement6
el7          el8          elel9
