+# PyArrow provides the following types:

+# - Numeric types:
+#   - int8, int16, int32, int64
+#   - uint8, uint16, uint32, uint64
+#   - float16, float32, float64
+#
+# In PyArrow, array types can be specified in two ways:

+# - Using string aliases (e.g., "int8")
+# - Using pyarrow.DataType (e.g., ``pa.int8()``)
