我需要将Excel工作表的第一列转换为整数值。需要删除字符串(比如LP001005,删除LP并获取数字的其余部分)。
我能够在单个变量上实现这一点。但是,我需要在Excel工作表上实现这一点。我的意思是将整个Excel转换为LP001005中的数据帧,提取Loan_ID并进行转换(从pandas中删除LP ),然后使用数据帧。
>>> import re
>>> test_str = "Geeks4321"
>>> print("The original string is : " + str(test_str))
The original string is : Geeks4321
>>> res = [re.findall(r'(\d+)', test_str)[0] ]
>>> print("The tuple after the split of string and number : " + str(res))
The tuple after the split of string and number : ['4321']
>>>Excel工作表如下所示:
LoanID Name
LP1401 Shubhra
LP1102 Ankit

您可以使用.extract()方法提取贷款ID的数字部分:
df = pd.DataFrame({'LoanID': 'LP1401 LP2102 LP3203'.split(),
'Name': 'Shubhra Ankit Sowmya'.split()})
df['LoanID'] = df['LoanID'].str.extract( r'\w(\d+)', expand=False ).astype(int)
print(df)
LoanID Name
0 1401 Shubhra
1 2102 Ankit
2 3203 Sowmya发布于 2020-08-18 08:42:53
在Jupyter上试试这个:
import pandas as pd
# open your excel file with pandas with the (read_excel) method:
f= pd.read_excel('Book1.xlsx',sheet_name='Sheet1')
# you may check the content of the first column:
for i in f.iloc[:,0]:
print(i)
# check the headers names as objects:
f.columns.ravel()
# finally extract the numbers from the first column:
f['LoanID '].str.extract('(\d+)')https://stackoverflow.com/questions/63459550
