【问题描述】：
所以我已经在网上搜索了一段时间，试图找到清理和合并一组准备工作的 .csv 文件的最佳方法。我已经设法获得了一些可以满足我需求的代码，但它并不完整，它在运行时基本上什么都不做。这是我迄今为止的清洁工作：
import pandas as pd
import numpy as np
#pick out empty spaces in the csv file
missing_values = ["--", " ", "0","-"]
dff = pd.read_csv("principal_offence_category_august_2014.csv", na_values = missing_values)
print(dff['Percentage of Homicide Convictions'])
print(dff['Percentage of Homicide Convictions'].isnull())
#detecting numbers
cnt=0
for row in dff['Percentage of Homicide Convictions']:
try:
int(row)
dff.loc[cnt, 'Percentage of Homicide Convictions'] = np.nan
except ValueError:
pass
cnt = cnt + 1
#replace empty values with 0
dff['Percentage of Homicide Convictions'].fillna(0, inplace=True)
#drop row with nan
dff = dff.dropna()
print(dff)
代码输出：
RESTART: C:\Users\Kinkerman\Downloads\Uni\Data Analytics\Dataset_Assignment\2014\Combine mod.py
我的合并代码也有问题，它什么也没返回。而且我不确定如何标记它们以便在合并时区分它们。这是我的代码：
import pandas as pd
path = "C:/Users/Kinkerman/Downloads/Uni/Data Analytics/Dataset_Assignment/2014"
part1 = pd.read_csv("principal_offence_category_april_2014.csv")
part2 = pd.read_csv("principal_offence_category_august_2014.csv")
part3 = pd.read_csv("principal_offence_category_december_2014.csv")
part4 = pd.read_csv("principal_offence_category_february_2014.csv")
part5 = pd.read_csv("principal_offence_category_january_2014.csv")
part6 = pd.read_csv("principal_offence_category_july_2014.csv")
part7 = pd.read_csv("principal_offence_category_june_2014.csv")
part8 = pd.read_csv("principal_offence_category_march_2014.csv")
part9 = pd.read_csv("principal_offence_category_may_2014.csv")
part10 = pd.read_csv("principal_offence_category_november_2014.csv")
part11 = pd.read_csv("principal_offence_category_october_2014.csv")
part12 = pd.read_csv("principal_offence_category_september_2014.csv")
combined_csv = pd.concat([part1, part2, part3, part4, part5, part6, part7, part8, part9, part10, part11, part12])
combined_csv.drop(["Unnamed: 0"], inplace=True, axis=1)
combined_csv.to_csv("principal_offence_year_2014")
代码输出：
什么都没有

我希望在一个地方获得一个包含所有月份的单个文件，这样我就可以对其进行数据分析。

欢迎来到 SO，如果您希望获得帮助，您的帖子需要一些改进。请阅读How to Ask 并写一个minimal reproducible example。此时社区将不得不猜测。因为没有输入样本，所以没有预期的输出定义。
-
你的合并代码“什么都不返回”是什么意思？示例代码中没有“return”语句。您是否验证了最初从磁盘读取的每个部分中的记录数？在combined_csv 中？在下降（）之后？写入磁盘？请更新每个阶段的记录数，并说明问题所在。

@SarahMesser 是的，这是正确的，但它应该输出到一个文件（“principal_offence_year_2014.csv”）并且它不这样做。此外，之前的 44 条和之后的 44 条记录的数量完全相同，但由于它的输出方式，我看不出它是否真的进行了任何更改。做单列时效果很好，但完整的代码会返回整个文件，所以我实际上看不到更改。
-
请发布数据样本，以及所需的输出。

@RJAdriaansen 我基本上是在清理空白空间的数据集，准备完成散点图，并推断相关性。使用一张年表中的所有月度数据，这个过程会容易得多吗？
