You can use the ListFields function in arcpy to obtain the field information of the table in GDB, including name, length and type. The sample code is as follows:
import arcpy
# 设置工作空间
arcpy.env.workspace = r"C:\data\myGDB.gdb"
# 获取表名
table_name = "myTable"
# 获取字段列表
fields = arcpy.ListFields(table_name)
# 遍历字段列表,输出字段名称、长度和类型
for field in fields:
print("Field Name: {}".format(field.name))
print("Field Length: {}".format(field.length))
print("Field Type: {}".format(field.type))
Among them, arcpy.ListFields(table_name)
the function returns a list of field objects, and the name, length, type and other information of each field can be obtained by traversing the list.
