python 读写 yaml格式文件的 demo

关于 python 读写 yaml格式文件的 demo：

1. 创建 yaml

import os
import yaml
aa = {
	"A":"aaaaa",
	"B":"bbb",
	"C":"cc",
	"n":"2",
	"names":["a","b"]
	}
curpath = os.path.dirname(os.path.realpath(__file__))
yamlpath = os.path.join(curpath, "./yamlFile/test.yaml")
with open(yamlpath,"w",encoding='utf-8') as f :
	# yaml.dump({"projects": aa}, f)
	yaml.safe_dump({"projects": single_product}, f, default_style=False, allow_unicode=True)

2. 修改yaml

import os
import yaml

def set_data(status_num):
	file_name = "./yamlFile/test.yaml"
curpath = os.path.dirname(os.path.realpath(__file__))
yamlpath = os.path.join(curpath, "./yamlFile/test.yaml")
with open(file_name) as f :
	docum = yaml.safe_load(f)
	docum["n"] = status_num
	with open(file_neme, 'w') as f:
		yaml.safe_dump(docum, f, default_style=False, allow_unicode=True)


set_data(8)  # 将 1 中的  n = 2  修改 为 n = 8
