用Python生成结果表

Question

juvenile0 = int(input("enter value"))
adult0 = int(input("enter value"))
senile0 = int(input("enter value"))
birth = int(input("enter value"))

#generation 1 formulae
juvenile1 = adult0 * birth
adult1 = juvenile0 * 0.5
senile1 = adult0 + (senile0 * 0.2)
#generation 2 formulae
juvenile2 = adult1 * birth
adult2 = juvenile1 * 0.5
senile2 = adult1 + (senile1 * 0.2)
#generation 3 formulae
juvenile3 = adult2 * birth
adult3 = juvenile2 * 0.5
senile3 = adult2 + (senile2 * 0.2)
#generation 4 formulae
juvenile4 = adult3 * birth
adult4 = juvenile3 * 0.5
senile4 = adult3 + (senile3 * 0.2)
#generation 5 formulae
juvenile5 = adult4 * birth
adult5 = juvenile4 * 0.5
senile5 = adult4 + (senile4 * 0.2)

print("____________________________________________")
print("|generations  |juveniles|  adults | seniles |")
print("|_____________|_________|_________|_________|")
print("|generation 0 |  ""%.2f" % juvenile0,"  | ""%.2f" % adult0,"   | ""%.2f" % senile0,"   |")
print("|_____________|_________|_________|_________|")
print("|generation 1 |  ""%.2f" % juvenile1,"  | ""%.2f" % adult1,"   |      ""%.2f" % senile1,"   |")
print("|_____________|_________|_________|_________|")
print("|generation 2 |  ""%.2f" % juvenile2,"  | ""%.2f" % adult2,"   | ""%.2f" % senile2,"   |")
print("|_____________|_________|_________|_________|")
print("|generation 3 |  ""%.2f" % juvenile3,"  | ""%.2f" % adult3,"   | ""%.2f" % senile3,"   |")
print("|_____________|_________|_________|_________|")
print("|generation 4 |  ""%.2f" % juvenile4,"  | ""%.2f" % adult4,"   | ""%.2f" % senile4,"   |")
print("|_____________|_________|_________|_________|")
print("|generation 5 |  ""%.2f" % juvenile5,"  | ""%.2f" % adult5,"   |  ""%.2f" % senile5,"  |")

我想知道用python创建表的最有效方法。我现在的代码可以工作，但是当用户输入更大的数字时，表格开始中断。有没有一种更简洁的方法可以用python创建表？在

Answer 1

你不重新发现方向盘而使用已经存在的东西怎么样？在

例如，您可以使用：

• tabulate出现在{a2}
• pandas还可以很好地打印出数据帧

Answer 2

您可以使用这个库：https://pypi.python.org/pypi/tabulate

from tabulate import tabulate

table = [
    ['generations', 'juveniles', 'adults', 'seniles'],
    ['generation 0', '%.2f' % juvenile0, '%.2f' % adult0, '%.2f' % senile0]
]
print(tabulate(table, tablefmt='grid'))
