使用python跳过csv.file中的第一行（当它是字符串时）

Question

我试图跳过csv.NET文件中的第一行，格式如下：

#utm32Hetrs89_h_dvr90
667924.1719,6161062.7744,-37.15227
 667924.9051,6161063.4086,-37.15225
 667925.6408,6161064.0452,-37.15223
 667926.2119,6161064.6107,-37.15221
 667926.4881,6161065.0492,-37.15220
 667926.7642,6161065.4876,-37.15220
 667927.0403,6161065.9260,-37.15219
 667927.3164,6161066.3644,-37.15218

这是我目前的代码：

with open('C:\\Users\\Bruger\\Desktop\\dtu\\S\\data\\WL_geoid_values.txt',newline='') as file:
    readCSV = csv.reader(file, delimiter=',',skipinitialspace=True)
    header = next(readCSV)
    for row in readCSV:
        coordsx.append(float(row[0]))
        coordsy.append(float(row[1]))  
        h_gravs.append(float(row[2]))

我收到一个错误，说我不能将字符串转换为浮点。在我开始读取行之前，如何确保它实际上跳过了第一行

我谦虚地建议使用pandas来读取CSV文件。您可以在几行中定义要跳过的行和格式：

import pandas as pd

# One single line to read all the data with the right format
df = pd.read_csv('C:\\Users\\Bruger\\Desktop\\dtu\\S\\data\\WL_geoid_values.txt', 
                 skiprows = 1,                           # Skip first row
                 names = ['coordsx','coordsy','h_gravs'] # Rename each column
                )

# Separating each column and turning then into lists
coordsx = df['coordsx'].tolist()
coordsy= df['coordsy'].tolist()
h_gravs= df['h_gravs'].tolist()
