python中 yaml.dump 对dict dump成yaml文件时,给特定字符串保留(加上)单引号

python yaml dict对str类型加上单引号
源数据:
dict1 = {"user_id": 23026, "contact": [{"name": "phone", "regexpr": "(^(0\d{2}-\d{8}(-\d{1,4})?)|(0\d{3}-\d{7,8}(-\d{1,4})?))|(^((13[0-9])|(14[5|7])|(15([0-3]|[5-9]))|(18[0,5-9]))\d{8})[ ]*$"}] }
python脚本:
import yaml def quoted_presenter(dumper, data): return dumper.represent_scalar('tag:yaml.org,2002:str', u'%s' % data, style="'") yaml.add_representer(str, quoted_presenter) yaml.dump(dict1, sys.stdout, width=1200, default_flow_style=False, sort_keys=False)
运行结果如下:str类型的都加上了单引号,数字没有
'user_id': 23026 'contact': - 'name': 'phone' 'regexpr': '(^(0\d{2}-\d{8}(-\d{1,4})?)|(0\d{3}-\d{7,8}(-\d{1,4})?))|(^((13[0-9])|(14[5|7])|(15([0-3]|[5-9]))|(18[0,5-9]))\d{8})[ ]*$'
python yaml dict对某个特定字符串加上单引号
源数据同上
python脚本:
import re pattern = re.compile(r'regexpr|' + re.escape( '(^(0\d{2}-\d{8}(-\d{1,4})?)|(0\d{3}-\d{7,8}(-\d{1,4})?))|(^((13[0-9])|(14[5|7])|(15([0-3]|[5-9]))|(18[0,5-9]))\d{8})[ ]*$') + r'|user_id') # pattern = re.compile(r'expr|user_id') #对expr和user_id加上单引号 # pattern = re.compile(r'|') #对所有的str类型加上单引号 yaml.add_implicit_resolver(None, pattern) yaml.dump(dict1, sys.stdout, width=1200, default_flow_style=False, sort_keys=False)
运行结果如下:user_id、regexpr和后边那串正则表达式加上了单引号。expr本身是正则,用re.escapte就可以把这些字符自动转义,再用re.compile.
'user_id': 23026 contact: - name: phone 'regexpr': '(^(0\d{2}-\d{8}(-\d{1,4})?)|(0\d{3}-\d{7,8}(-\d{1,4})?))|(^((13[0-9])|(14[5|7])|(15([0-3]|[5-9]))|(18[0,5-9]))\d{8})[ ]*$'
