1 yaml.full_load()
- 源码:
- 作用:解析流中的第一个
YAML
文档并生成相应的Python
对象;解析所有标记,不包括那些在不受信任的输入中已知不安全的标记。 - 解析:

import yaml
with open('config_pyyaml02.yaml', 'r') as f:
data = yaml.full_load(f)
print(data)
- 输出:

2 yaml.full_load_all()
- 源码:
- 作用:解析流中的所有
YAML
文档并生成相应的Python
对象;解析所有标记,不包括那些在不受信任的输入中已知不安全的标记。 - 解析:
# config_yaml03.yaml如下:
---
user1:
name: xiaoming
age: 23
password: 123456
---
user2:
name: xiaozhang
age: 24
password: 123456
---
user3:
name: xiaoli
age: 25
password: 123456

import yaml
f = open('config_pyyaml03.yaml', 'r')
docs = yaml.full_load_all(f)
for doc in docs:
print(doc)
f.close()
- 输出:
{
'user1': {
'name': 'xiaoming', 'age': 23, 'password': 123456}}
{
'user2': {
'name': 'xiaozhang', 'age': 24, 'password': 123456}}
{
'user3': {
'name': 'xiaoli', 'age': 25, 'password': 123456}}
3 yaml.safe_load()
源码:
作用:
解析流中的第一个YAML文档,并生成相应的Python对象。只解析基本的YAML标记。这是已知的对于不可信的输入是安全的。
- 解析:
# config_pyyaml04.yaml
{
name: John Doe,
age: 28,
hobbies: [hiking, cooking, fishing],
address:
{
city: New York,
state: NY,
street: 100 Main St,
location:
{
longitude: 40.712776,
latitude: -74.005974
}
},
family:
[
{
name: Jane,
age: 25,
relation: spouse
},
{
name: Joe,
age: 3,
relation: son
}
]
}

'name': 'Joe', 'age': 3, 'relation': 'son'}]}
4 yaml.unsafe_load()
- 源码:
- 作用:
解析流中的第一个YAML文档,并生成相应的Python对象。解析所有标签,即使是已知的不受信任的输入不安全。
5 yaml.unsafe_load_all()
- 源码:
- 作用:
分析流中的所有YAML文档,并生成相应的Python对象。解析所有标签,即使是已知的不受信任的输入不安全。
