我一直在尝试做一个个人项目(project1的一个专门版本，来自Python自动化枯燥的东西，但特别是在我国提取这种格式的电话号码)

可接受的格式为：

手机号码-

(+91或91)可选，可以用括号括起来，也可以不用

后跟可选空格(\s)？后面是10位数字

固定电话号码-

3位区号(\d\d\d)？可选择的

后跟空格或连字符(\s或-)可选

后面是8位数字

带国家代码的固定电话号码-

(+91或91)可选，可以用括号括起来，也可以不用

后跟(\s或-)可选

后跟2位代码(\d\d)

后跟(\s或-)可选

后面是8位数字

我写的剧本是-import re,pyperclip,os,datetime

#Regexes for phone numbers.

cellphone = re.compile(r'((91|+91|\(+91\))?\s?\d{10})')

landline = re.compile(r'((\d{3}|\(d{3}\))?(-|\s)(\d{8}))')

landline_with_countrycode = re.compile(r'((91|+91|\(+91\))(-|\s)(\d{2})(-|\s)?(\d{8}))')

#Taking input from clipboard

text = str(pyperclip.paste())

cell_nums = []

for groups in cellphone.findall(text):

cell_nums.append(groups[0])

ll_nums = []

for groups in cellphone.findall(text):

ll_nums.append(groups[0])

ll_nums_wccode = []

for groups in cellphone.findall(text):

ll_nums_wccode.append(groups[0])

#Sending output to a file that was created on Desktop in folder abswpy named phnumbers.log

file_path = os.path.join("C:","Users","lenovo","Desktop","abswpy","phnumbers.log")

openFile = open(file_path,'a')

now = datetime.datetime.now()

openFile.write('______________________________________________________________________________________________________\n\n')

openFile.write('\n\n As updated on '+str(now)+'\n\n')

openFile.write('---------------------------------------------------------\n')

openFile.write('Cellphone Numbers - \n')

for i in cell_nums:

openFile.write(str(i))

openFile.write('---------------------------------------------------------\n')

openFile.write('Landline Numbers - \n')

for i in ll_nums:

openFile.write(str(i))

for i in ll_nums_wccode:

openFile.write(str(i))

openFile.write('---------------------------------------------------------\n')

openFile.write('Process Completed')

openFile.write('______________________________________________________________________________________________________\n\n')

openFile.close()

print "Numbers extracted if present\n"

代码给出编译时错误-

^{pr2}$

为什么我的表达式计算错误？

提前谢谢你的帮助，我只是个初学者！在
