函数功能：
读取csv文件，每隔20行取一行，写入新的csv文件。
def InterlacedAccess(read_path,write_path):
import pandas as pd
# read_path = r'E:datamanual处理后20211127093020.csv'
# write_path =r'E:datamanualprocessData处理后20211127093020.csv'
data = pd.read_csv(read_path,encoding='gbk') #解决中文字符乱码问题
df = pd.Dataframe(data)
a=[]
for i in range(0,len(df),20):##每隔20行取数据
a.append(i)
file = df.iloc[a]
f = pd.Dataframe(file)
f.to_csv(write_path, index=False,encoding='utf_8_sig')
print('ok')
