我有一个很大的csv数据文件,我想使用列进行分割。也就是说,一些指定的列进入一个部分,其他一些列进入另一部分。我也希望能够创建2个以上的零件。我如何在Python中做到这一点?另外,是否有一个python库来处理多种数据格式?如何使用列名称将csv拆分为多个部分?
输入格式:
policyID statecode county eq_site_limit hu_site_limit fl_site_limit fr_site_limit tiv_2011 tiv_2012 eq_site_deductible hu_site_deductible fl_site_deductible fr_site_deductible point_latitude point_longitude line construction point_granularity

输入格式色谱柱:
policyID statecode county eq_site_limit hu_site_limit fl_site_limit fr_site_limit tiv_2011 tiv_2012 eq_site_deductible hu_site_deductible fl_site_deductible fr_site_deductible point_latitude point_longitude line construction point_granularity
输出格式色谱柱:
部分A:['policyID', 'statecode', 'county', 'eq_site_limit', 'hu_site_limit']
部分B:['fl_site_limit', 'fr_site_limit', 'tiv_2011', 'tiv_2012', 'eq_site_deductible', 'hu_site_deductible', 'fl_site_deductible', 'fr_site_deductible', 'point_latitude', 'point_longitude', 'line', 'construction', 'point_granularity']
代码:
import csv
import pandas as pd
df = pd.read_csv("FL_insurance_sample.csv")
cl_list = list(df.columns.values)
a = cl_list[:5]
b = cl_list[5:]
with open('data1.csv', 'w') as datafile:
for x in a:
saved_column = df[x]
datafile.write(saved_column)
with open('data2.csv', 'w') as datafile:
for x in b:
saved_column = df[x]
datafile.write(saved_column)
我们需要查看csv文件的示例以及您尝试处理它的代码。 –
还有一些指示输出必须具有的格式。 –
“许多数据格式”是什么意思? – DyZ
