将pandas中的整列数字转换为等价的单词

import pandas as pd

# 创建数字和单词的字典映射关系
mapping = {
    1: 'one',
    2: 'two',
    3: 'three',
    4: 'four',
    5: 'five'
}

# 创建包含数字的DataFrame
df = pd.DataFrame({'numbers': [1, 2, 3, 4, 5]})

# 使用replace方法将数字替换为对应的单词
df['words'] = df['numbers'].replace(mapping)

print(df)

   numbers  words
0        1    one
1        2    two
2        3  three
3        4   four
