Python中的华氏温度到摄氏温度

Question

我试图将数据集（'weatherData.csv'）从华氏温度传输到摄氏温度，但失败了

代码：

temp_f= weatherData[:,0] # temperature in Fahrenheit
print(temp_f)

输出：

print(convert_c(temp_f))
[ 47.97057286  23.5196821   62.83761601  29.76327695  62.6681284

如何将这些数据传输到摄氏度？谢谢

Answer 1

试试这个：

def to_celsius(fah):
    fah -= 32
    return fah / 1.8

data = [47.97057286, ... ]
new_data = list(map(to_celsius, data))
print(new_data)

# [8.872540477777775, ... ]
