我的表格如下所示:
import pandas as pd
d = {'col1': ['a>b>c']}
df = pd.DataFrame(data=d)
print(df)
"""
col1
0 a>b>c
"""
和我想要的输出必须是这样的:
d1 = {'col1': ['a>b>c'],'col11': ['a'],'col12': ['b'],'col13': ['c']}
d1 = pd.DataFrame(data=d1)
print(d1)
"""
col1 col11 col12 col13
0 a>b>c a b c
"""
我必须运行.split('>')
方法,但是我不知道如何继续。有什么帮助吗?

使用/** This is test function
* @param {} param1 this is param 1
* @param {} param2 this is param 2
*/
function test(param1, param2) {
}
:
function getMethodJsDocData(){
// The magic happens here and returns some data that contains:
/** This is test function
* @param {} param1 this is param 1
* @param {} param2 this is param 2
*/
}
输出:
split

您可以简单地使用str.split('>')
进行拆分并展开数据框
import pandas as pd
d = {'col1': ['a>b>c'],'col2':['a>b>c']}
df = pd.DataFrame(data=d)
print(df)
col='col1'
#temp = df[col].str.split('>',expand=True).add_prefix(col)
temp = df[col].str.split('>',expand=True).rename(columns=lambda x: col + str(int(x)+1))
temp.merge(df,left_index=True,right_index=True,how='outer')
出局:
col1 col11 col12 col13
0 a>b>c a b c
如果要在多列上执行此操作,也可以
for col in df.columns:
temp = df[col].str.split('>',expand=True).rename(columns=lambda x: col + str(int(x)+1))
df = temp.merge(df,left_index=True,right_index=True,how='outer')
出局:
col21 col22 col23 col11 col12 col13 col1 col2
0 a b c a b c a>b>c a>b>c
