How to write temperature conversion in python123

Python provides multiple methods for converting temperature units: use the numpy.convert_units() function in the NumPy library: import NumPy and use convert_units for conversion. Use the pandas.to_numeric() function in the Pandas library: import Pandas and use to_numeric to intelligently convert the temperature. Use custom functions: Create custom functions fahrenheit_to_celsius and celsius_to_fahrenheit for conversion.

Temperature conversion in Python

Python provides a variety of methods to convert temperature units:

Using NumPy

The numpy.convert_units() function in the NumPy library can be used to convert temperature units:

<code class="python">import numpy as np

# 从华氏度转换为摄氏度
celsius = np.convert_units(100, 'degF', 'degC')

# 从摄氏度转换为华氏度
fahrenheit = np.convert_units(37, 'degC', 'degF')</code>

Using Pandas

The pandas.to_numeric() function in the Pandas library can intelligently convert temperature units:

<code class="python">import pandas as pd

# 从华氏度转换为摄氏度
celsius = pd.to_numeric("100 degF", unit='degF', errors='coerce')

# 从摄氏度转换为华氏度
fahrenheit = pd.to_numeric("37 degC", unit='degC', errors='coerce')</code>

Use custom functions

You can also create a custom function to convert temperature units:

<code class="python">def fahrenheit_to_celsius(fahrenheit):
    """将华氏度转换为摄氏度"""
    return (fahrenheit - 32) * 5/9

def celsius_to_fahrenheit(celsius):
    """将摄氏度转换为华氏度"""
    return celsius * 9/5 + 32</code>

Example

Here's how to convert temperature units using these methods:

<code class="python"># NumPy
fahrenheit_value = 100
celsius_value = np.convert_units(fahrenheit_value, 'degF', 'degC')
print("华氏度:", fahrenheit_value, "摄氏度:", celsius_value)

# Pandas
fahrenheit_value = "100 degF"
celsius_value = pd.to_numeric(fahrenheit_value, unit='degF', errors='coerce')
print("华氏度:", fahrenheit_value, "摄氏度:", celsius_value)

# 自定义函数
fahrenheit_value = 100
celsius_value = fahrenheit_to_celsius(fahrenheit_value)
print("华氏度:", fahrenheit_value, "摄氏度:", celsius_value)</code>
