python常用代码
1.excel某一列转为list
def excel_one_line_to_list(standard_anytunnel):
result = []
df = pd.read_excel(standard_anytunnel, usecols=[9], names=None) # 读取第9列,不要列名
df_li = df.values.tolist()
for s_li in df_li:
result.append(s_li[0])
return result
2.实现vlookup功能
def add_vip_status(src_File, des_Flie):
df_grade = pd.read_excel(src_File)
df_grade.head()
df_sinfo = pd.read_excel(des_Flie)
df_sinfo.head()
# 筛选第二张表少量列
df_sinfo = df_sinfo[["any_tunnel_vip", "status"]]
df_sinfo.head()
df_merge = pd.merge(left=df_grade, right=df_sinfo, left_on="vip", right_on="any_tunnel_vip")
df_merge.head()
df_merge.to_excel("result.xls", index=False)
3.原有sheet表新增一列
def add_tunnel_type(result_file):
workbook = xlrd.open_workbook(result_file)
sheet1 = workbook.sheet_by_name('Sheet1')
newbook = copy(workbook)
newsheet = newbook.get_sheet(0)
for index in range(sheet1.nrows):
if index == 0:
newsheet.write(index, 20, label='tunnel_type')
else:
newsheet.write(index, 20, label='anytunnel')
newbook.save(result_file)
4.python读取xml格式的xls文件
用xlrd读xls类型的文件,结果一直报错
xlrd.biffh.XLRDError: Unsupported format, or corrupt file: Expected BOF record; found b'<?xml ve'
def html_to_xls(html_file):
# 拿到xls文件内容
html = open(html_file, 'r').read()
# 转换为真正xls格式excel
try:
df = pd.read_html(html)
bb = pd.ExcelWriter(vip_file)
df[0].to_excel(bb)
bb.close()
except Exception as e:
pass
5.python按行读取txt内容
def read_text(self):
current_path = os.path.abspath(__file__)
ip_txt = os.path.abspath(os.path.dirname(current_path) + os.path.sep + ".") + '/../conf/ip.txt'
ip_content = []
with open(ip_txt, 'r') as f:
for line in f.readlines():
line = line.strip('\r\n') # 去掉列表中每一个元素的换行符
ip_content.append(line)
str_ip_content = ','.join(ip_content)
return str_ip_content
