根据定义列表中的输入定义pandas列中的范围

import pandas as pd

# 创建一个空的数据框
df = pd.DataFrame()

definitions = [
    {'name': 'age', 'type': 'int', 'min': 0, 'max': 100},
    {'name': 'height', 'type': 'float', 'min': 0.0, 'max': 2.5},
    {'name': 'name', 'type': 'str'}
]

for definition in definitions:
    name = definition['name']
    col_type = definition['type']
    if col_type == 'int':
        min_val = definition['min']
        max_val = definition['max']
        df[name] = pd.Series(pd.np.random.randint(min_val, max_val + 1, size=10))
    elif col_type == 'float':
        min_val = definition['min']
        max_val = definition['max']
        df[name] = pd.Series(pd.np.random.uniform(min_val, max_val, size=10))
    elif col_type == 'str':
        df[name] = pd.Series(['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J'])

print(df)
