如何从Python的字符串中删除数字 – Pandas?
在本文中,让我们看看如何在 Pandas 中从字符串中删除数字。目前,我们将仅使用 .csv 文件进行演示,但其他类型的文件的过程是相同的。函数read_csv()用于读取 CSV 文件。
Syntax:
for the method ‘replace()’:
str.replace(old, new)
这里 str。 replace() 将返回一个字符串,其中参数 'old' 将被参数 'new' 替换。现在让我们通过编码看看如何从 Pandas 数据框中的字符串中删除数字。
示例 1:
Python3
# code
import pandas as pd
# creating dataframe
df = pd.DataFrame.from_dict({'Name': ['May21', 'James',
'Adi22', 'Hello',
'Girl90'],
'Age': [25, 15, 20, 33, 42],
'Income': [21321, 12311, 25000,
32454, 65465]})
# removing numbers from strings of speciafied
# column, here 'Name'
df['Name'] = df['Name'].str.replace('\d+', '')
# display output with numbers removed from
# required strings
print(df)
Python3
# code
import pandas as pd
# creating dataframe
df = pd.DataFrame.from_dict({'Name': ['rohan21', 'Jelly',
'Alok22', 'Hey65',
'boy92'],
'Age': [24, 25, 10, 73, 92],
'Income': [28421, 14611, 28200,
45454, 66565]})
# removing numbers from strings of speciafied
# column, here 'Name'
df['Name'] = df['Name'].str.replace('\d+', '')
# display output with numbers removed from
# required strings
print(df)
输出:

'Income': [28421, 14611, 28200,
