Анализируйте данные на предмет максимальной ширины и используйте форматирование строки - некоторое «творческое» форматирование позже:
data = [
(
1,
u'python -c \'print("ok")\'',
u'data',
u'python'
), (
2,
u'python -c \'print("this is some data")\'',
u'data',
u'python'
)
]
def print_table(data):
widths = {0:0, 3:len("Language"),2:len("Type"),1:len("Payload")}
for k in data:
for i,d in enumerate(k):
widths[i] = max(widths[i],len(str(d)))
# print(widths)
lan, typ, pay = ["Language","Type","Payload"]
print(f"{lan:<{widths[3]}} | {typ:<{widths[2]}} | {pay:<{widths[1]}}")
# adjust by 10 for ' | ' twice
print("-" * (widths[1]+widths[2]+widths[3]+10))
for k in data:
_, pay, typ, lan = k
print(f"{lan:<{widths[3]}} | {typ:<{widths[2]}} | {pay:<{widths[1]}}")
Вывод:
Language | Type | Payload
------------------------------------------------------------
python | data | python -c 'print("ok")'
python | data | python -c 'print("this is some data")'
Эквивалентный код Python 2.7:
# w == widths - would break 79 chars/line else wise
def print_table(data):
w = {0:0, 3:len("Language"),2:len("Type"),1:len("Payload")}
for k in data:
for i,d in enumerate(k):
w[i] = max(w[i],len(str(d)))
lan, typ, pay = ["Language","Type","Payload"]
print "{:<{}} | {:<{}} | {:<{}}".format(lan, w[3], typ, w[2], pay, w[1])
print "-" * (w[1]+w[2]+w[3]+10)
for k in data:
_, pay, typ, lan = k
print "{:<{}} | {:<{}} | {:<{}}".format(lan, w[3], typ, w[2], pay, w[1])
