Write a Pandas program to extract only number from the specified column of a given DataFrame. Sample Solution:Python Code :import pandas as pd import re as re pd.set_option('display.max_columns', 10) df = pd.DataFrame({ 'company_code': ['c0001','c0002','c0003', 'c0003', 'c0004...
# A limit to the number of cells (rows * columns) that can be downloaded from a query # (e.g. - 10K rows * 1K columns = 10M cells.) # A value of -1 means there will be no limit. download_cell_limit=100 我们注释掉该配置项之后,重启hue服务,测试csv和excel都可以正常下载,问题解决...
