如何在Python中打开.stg文件?
我在Spyder中使用Python3.8读取扩展名为“.stg”的数据文件。这些文件是地球物理中使用的一些设备的输出。到目前为止,我找到的唯一选项是在文本编辑器(记事本)中手动打开文件,将其另存为.txt,最后使用以下代码行:如何在Python中打开.stg文件?,python,pandas,txt,Python,Pandas,Txt,我在Spyder中使用Python3.8读取扩展名为“.stg”的数据文件。这些文件是地球物理中使用的一些设备的输出。到目前为止,我找到的唯一选项是在文本编辑器(记事本)中手动打开文件,将其另存为.txt,最后使用以下代码行: 将熊猫作为pd导入 df=pd.read\u csv('TSC16.txt',header=3) 文件可以很好地打开,但我想知道是否有一种有效的方法来打开它,因为最终,我的目标是处理大量的.stg文件。 谢谢你的帮助 STG文件是一个纯文本文件,它有三行元数据,然后是一个
将熊猫作为pd导入
df=pd.read\u csv('TSC16.txt',header=3)
文件可以很好地打开,但我想知道是否有一种有效的方法来打开它,因为最终,我的目标是处理大量的.stg文件。
谢谢你的帮助 STG文件是一个纯文本文件,它有三行元数据,然后是一个逗号分隔的值表。您可以使用pd阅读此内容。按您所掌握的方式阅读。您需要设置列名,您可以找到这些列名。我已经将它们包含在下面的代码中
import pandas as pd
columns = [
'data record number',
'USER',
'date (YYYYMMDD)',
'time (hh:mm:ss)',
'V/I',
'% error in tenths of percent',
'output current in mA',
'apparent resistivity in Ωm or Ωft',
'command file identifier',
'X-coordinate for the A-electrode',
'Y-coordinate for the A-electrode',
'Z-coordinate for the A-electrode',
'X-coordinate for the B-electrode',
'Y-coordinate for the B-electrode',
'Z-coordinate for the B-electrode',
'X-coordinate for the M-electrode',
'Y-coordinate for the M-electrode',
'Z-coordinate for the M-electrode',
'X-coordinate for the N-electrode',
'Y-coordinate for the N-electrode',
'Z-coordinate for the N-electrode',
'Cmd line number',
'Transmitter volt code',
'# of measurement cycles',
'Measurement time used',
'Gain setting',
'Channel used',
]
df = pd.read_csv("TSC16.stg", skiprows=3, header=None, names=columns)
数据帧必须稍微处理一下。两列后面有空格,六列包含前缀,如cmd=
。下面的代码处理这两件事
# Strip whitespace from some columns.
for colname in ["USER", "command file identifier"]:
df.loc[:, colname] = df.loc[:, colname].str.strip()
# Remove prefixes like 'cmd=' and convert to a numeric type.
for colname in ["Cmd line number", "Transmitter volt code", "# of measurement cycles",
"Measurement time used", "Gain setting", "Channel used"]:
df.loc[:, colname] = df.loc[:, colname].str.split("=", expand=True).iloc[:, -1].astype(float)
以下是此处理后数据帧的第一行:

不会更改文件的内容。您可以在任何文本编辑器中打开STG文件以查看其内容。为了清楚起见,这里是文件的前几行
