这是代码示例:
import numpy as np
import pandas as pd
import xlsxwriter
tuples = [('bar', 'one'), ('bar', 'two'), ('baz', 'one'), ('baz', 'two'), ('foo', 'one'), ('foo', 'two'), ('qux', 'one'), ('qux', 'two')]
index = pd.MultiIndex.from_tuples(tuples, names=['first', 'second'])
iterables = [['bar', 'baz', 'foo', 'qux'], ['one', 'two']]
pd.MultiIndex.from_product(iterables, names=['first', 'second'])
df = pd.DataFrame(np.random.randn(3, 8), index=['A', 'B', 'C'], columns=index)
print(df)
writer = pd.ExcelWriter('test.xlsx', engine='xlsxwriter')
df.to_excel(writer, sheet_name='test1')
现在如何摆脱第一列。
即使我没有提到index = ['A','B','C']或names = ['first','second']
它默认创建index = [0,1,2]
那么如何在创建excel时摆脱第一列。
这是5行修复 -
原始代码 -
tuples = [('bar', 'one'), ('bar', 'two'), ('baz', 'one'), ('baz', 'two'), ('foo', 'one'), ('foo', 'two'), ('qux', 'one'), ('qux', 'two')]
index = pd.MultiIndex.from_tuples(tuples, names=['first', 'second'])
iterables = [['bar', 'baz', 'foo', 'qux'], ['one', 'two']]
df = pd.DataFrame(np.random.randn(3, 8), columns=index)
在上面的代码之后添加新的5行 -
# Setting first column as index
df = df.set_index(('bar', 'one'))
# Removing 'bar', 'one' frm index name
df.index.name = ''
# Setting new columns Multiindex
tuples = [('', 'two'), ('baz', 'one'), ('baz', 'two'), ('foo', 'one'), ('foo', 'two'), ('qux', 'one'), ('qux', 'two')]
index_new = pd.MultiIndex.from_tuples(tuples, names=['bar', 'one'])
df.columns = index_new
稍后写你的excel就像 -
# Writing to excel file keeping index
writer = pd.ExcelWriter('test.xlsx', engine='xlsxwriter')
df.to_excel(writer, sheet_name='test1')
注意 - 细胞A1
和B1
没有合并只有一个小缺点。
