[英]Counting consonants and vowels in a split string
我读了一个 .csv 文件。 我有以下数据框,用于计算Description
列中字符串中的元音和辅音。 这很好用,但我的问题是我想将Description
分成 8 列并计算每列的辅音和元音。 我的代码的第二部分允许我将Description
分成 8 列。 我如何计算Description
分成的所有 8 列上的元音和辅音?
import pandas as pd
import re
def anti_vowel(s):
result = re.sub(r'[AEIOU]', '', s, flags=re.IGNORECASE)
return result
data = pd.read_csv('http://core.secure.ehc.com/src/util/detail-price-list/TristarDivision_SummitMedicalCenter_CM.csv')
data.dropna(inplace = True)
data['Vowels'] = data['Description'].str.count(r'[aeiou]', flags=re.I)
data['Consonant'] = data['Description'].str.count(r'[bcdfghjklmnpqrstvwxzy]', flags=re.I)
print (data)
这是我用来将列Description
拆分为 8 列的代码。
import pandas as pd
data = data["Description"].str.split(" ", n = 8, expand = True)
data = pd.read_csv('http://core.secure.ehc.com/src/util/detail-price-list/TristarDivision_SummitMedicalCenter_CM.csv')
data.dropna(inplace = True)
data = data["Description"].str.split(" ", n = 8, expand = True)
print (data)
现在我怎样才能把它们放在一起?
为了读取 8 的每一列并计算辅音,我知道我可以使用以下将 0 替换为 0-7:
testconsonant = data[0].str.count(r'[bcdfghjklmnpqrstvwxzy]', flags=re.I)
testvowel = data[0].str.count(r'[aeiou]', flags=re.I)
期望的输出是:
Description [0] vowel count consonant count Description [1] vowel count consonant count Description [2] vowel count consonant count Description [3] vowel count consonant count Description [4] vowel count consonant count all the way to description [7]
stack
然后unstack
stacked = data.stack()
pd.concat({
'Vowels': stacked.str.count('[aeiou]', flags=re.I),
'Consonant': stacked.str.count('[bcdfghjklmnpqrstvwxzy]', flags=re.I)
}, axis=1).unstack()
Consonant Vowels

如果要将其与data
框结合起来,可以执行以下操作:
stacked = data.stack()
pd.concat({
'Data': data,
'Vowels': stacked.str.count('[aeiou]', flags=re.I),
'Consonant': stacked.str.count('[bcdfghjklmnpqrstvwxzy]', flags=re.I)
}, axis=1).unstack()
