关于Pandas'Freq'标签的文档在哪里？

Question

我是Pandas的新手,我正在尝试使用date_range.我碰到各种各样的好东西来的freq,就像BME和BMS我希望能够快速查找正确的字符串来获得我想要的东西.昨天我在文档的某个地方找到了一个格式很好的表格,但是表格的标题太过于迟钝,以至于我今天无法使用搜索找到它.

Answer 1

您可以找到它称为偏移别名:

许多字符串别名被赋予有用的公共时间序列频率.我们将这些别名称为偏移别名(在v0.8.0之前称为时间规则).

Alias   Description
B       business day frequency
C       custom business day frequency (experimental)
D       calendar day frequency
W       weekly frequency
M       month end frequency
BM      business month end frequency
CBM     custom business month end frequency
MS      month start frequency
BMS     business month start frequency
CBMS    custom business month start frequency
Q       quarter end frequency
BQ      business quarter endfrequency
QS      quarter start frequency
BQS     business quarter start frequency
A       year end frequency
BA      business year end frequency
AS      year start frequency
BAS     business year start frequency
BH      business hour frequency
H       hourly frequency
T, min  minutely frequency
S       secondly frequency
L, ms   milliseonds
U, us   microseconds
N       nanoseconds

但后来它会更好:
