$ pip install redis

@pythonlstr_val = 'apples'
num_val = 42
print(f'{num_val} {str_val}') # 42 apples
2. Variable names
Apart from getting a variable's value, you can also get its name alongside the value.
str_val = 'apples'
num_val = 42
print(f'{str_val=}, {num_val = }') # str_val='apples', num_val = 42
3. Mathematical operations
Not syntactically unlike variable names, you can also perform mathematical operations in f-strings.
num_val = 42
print(f'{num_val % 2 = }') # num_val % 2 = 0
4. Printable representation
Apart from plain string interpolation, you might want to get the printable representation of a value.
str_val = 'apples'
print(f'{str_val!r}') # 'apples'
5. Number formatting
Numbers are a great candidate for this. If, for example, you want to trim a numeric value to two digits after the decimal, you can use the .2f format specifier.
price_val = 6.12658
print(f'{price_val:.2f}') # 6.13
6. Date formatting
Finally, dates can also be formatted the same way as numbers, using format specifiers. As usual, %Y denotes the full year, %m is the month and %d is the day of the month.
from datetime import datetime;
date_val = datetime.utcnow()
print(f'{date_val=:%Y-%m-%d}') # date_val=2021-07-09

▪F-strings или как сделать код чуть более быстрым
@pythonl
from pydantic import BaseModel
class User(BaseModel):
name: str
age: int
user = User(name='John Doe', age=30)
2. Default Values
Define default values for your model fields.
class User(BaseModel):
name: str
age: int = 18 # Default value
3. Optional Fields
Mark fields as optional using the Optional type.
from typing import Optional
class User(BaseModel):
name: str
age: Optional[int] = None
4. Custom Validators
Create custom validators with the @validator decorator.
from pydantic import validator
class User(BaseModel):
name: str
age: int
@validator('age')
def validate_age(cls, value):
if value < 18:
raise ValueError('User must be 18+')
return value
5. Nested Models
Use Pydantic models to validate nested data structures.
class Address(BaseModel):
street: str
city: str
class User(BaseModel):
name: str
age: int
address: Address
6. Lists of Models
Handle lists of a specific model.
from typing import List
class User(BaseModel):
name: str
age: int
class UserList(BaseModel):
users: List[User]
7. Union Fields
Use Union to allow a field to be one of several types.
from typing import Union
class User(BaseModel):
identifier: Union[str, int]
8. Value Constraints
Impose constraints on values using Field.
from pydantic import Field
class User(BaseModel):
name: str
age: int = Field(..., gt=0, lt=120) # Greater than 0, less than 120
9. Aliases for Fields
Define aliases for model fields, which can be useful for fields that are Python keywords.
class User(BaseModel):
name: str
class_: str = Field(alias='class')
10. Recursive Models
Make models that can contain themselves.
from typing import Optional
class TreeNode(BaseModel):
value: int
left: Optional['TreeNode'] = None
right: Optional['TreeNode'] = None
TreeNode.update_forward_refs() # Resolve string annotations
@pythonlimport numpy as np
a = np.array([[1, 2, 1], [2, 2, 5]])
# get the rows whose all values are fewer than 3
mask_all = (a<3).all(axis=1)
print(a[mask_all])
"""
[[1 2 1]]
"""
mask_any = (a<3).any(axis=1)
print(a[mask_any])
"""
[[1 2 1]
[2 2 5]]
"""
