文件对象提供了三个“读”方法： .read()、.readline() 和 .readlines()。每种方法可以接受一个变量...
3.File Dialog Button Lable :接确定按钮中的文本;Prompt:接弹出对话框提示;default name:接默认选中的名字;Pattern:接选择文件的类型,如*.txt、*.*;pattern name:接用户选择类型提示。 4.Read Text File 按图中进行txt文本写入和读取时,读取txt读取不到任何字符,并且未返回错误。该做法需要注意。 右键选择读取...

文件,组和通道可能都具有与之关联的属性,但是只有通道才具有数组数据。 读取TDMS文件时的典型用法如下所示: from nptdms import TdmsFile tdms_file = TdmsFile.read("path_to_file.tdms") group = tdms_file['group name'] channel = group['channel name'] channel_data = channel[:] channel_pro ...
使用python pandas读取LabVIEW TDMS文件的示例代码如下: 代码语言:txt 复制 import pandas as pd # 读取LabVIEW TDMS文件 df = pd.read_tdms('path/to/labview_file.tdms') # 打印DataFrame对象 print(df) 通过以上代码,可以将LabVIEW TDMS文件读取到一个名为df的DataFrame对象中,然后可以根据需要进行进一步的数...

Typical usage when reading a TDMS file might look like: from nptdms import TdmsFile tdms_file = TdmsFile.read("path_to_file.tdms") group = tdms_file['group name'] channel = group['channel name'] channel_data = channel[:] channel_properties = channel.properties The TdmsFile.read method...

TDMS文件以组和通道的层次结构进行构造。 TDMS文件可以包含多个组,每个组可以包含多个通道。 文件,组和通道可能都具有与之关联的属性,但是只有通道才具有数组数据。 读取TDMS文件时的典型用法如下所示: from nptdms import TdmsFile tdms_file = TdmsFile.read("path_to_file.tdms") ...
