利用pandas库, 将numpy的array数据保存成csv格式的文件: import pandas as pd import numpy as np data = pd.read_csv('C:\\abc\\a.csv', header=None) col1 = data.values[:,0] col2 = data.values[:,1]-0.9 for i in range(0, len(col2)): col2[i] = float("%.2f" % col2[i]) co
这个方法可以实现,登录获取的token放入CSV文件,供后续调用,这里没有用登录举例 FileWriter fstream = new FileWriter("E:\\apache-jmeter-5.0\\demo\\CSVDoc\\token.csv",true); BufferedWriter out = new BufferedWriter(fstream); out.write("code"+vars.get("name")+"
