如何使用tabulate包在python中合并多个表？

在python中连接两个表时，

append无效。这些表是使用python中的tabulate包实现的。

table_1 = [["Value_1",1,2],["Value_2",2,4],["Value_3",2,3]]
table_2 = [["Value_1",1,2],["Value_2",2,4],["Value_3",2,3]]
table_3 = table_1.append(table_2)
print table_3

Answer 1

对于“连接两个表”，您可能需要list.extend，而不是追加。追加将第二个列表作为单个项目插入第一个列表。另请注意，extend将就地修改源列表并返回None：

>>> table_1 = [["Value_1",1,2],["Value_2",2,4],["Value_3",2,3]]
>>> table_2 = [["Value_1",1,2],["Value_2",2,4],["Value_3",2,3]]
>>> table_3 = table_1.extend(table_2)
>>> print table_3
None

table_3现在为None，而table_1已延长：

>>> print table_1
[['Value_1', 1, 2], ['Value_2', 2, 4], ['Value_3', 2, 3], ['Value_1', 1, 2], ['Value_2', 2, 4], ['Value_3', 2, 3]]

Answer 2

list.append或extend在列表中改变列表并返回None，因此您的table_3会在其中获得None。您可以使用+添加连接两个列表：

In [251]: table_1 = [["Value_1",1,2],["Value_2",2,4],["Value_3",2,3]]
     ...: table_2 = [["Value_1",1,2],["Value_2",2,4],["Value_3",2,3]]
     ...: table_3 = table_1 + table_2
     ...: print table_3
[['Value_1', 1, 2], ['Value_2', 2, 4], ['Value_3', 2, 3], ['Value_1', 1, 2], ['Value_2', 2, 4], ['Value_3', 2, 3]]

Answer 3

您可以应用追加，因为值将采用列表格式..........

table_1 = [[＆＃34; Value_1＆＃34;，1,2]，[＆＃34; Value_2＆＃34;，2,4]，[＆＃34; Value_3＆＃34;，2,3] ] table_2 = [[＆＃34; Value_1＆＃34;，1,2]，[＆＃34; Value_2＆＃34;，2,4]，[＆＃34; Value_3＆＃34;，2,3]] table_1.extend（TABLE_2） print table_1
