python将dataFrame转化为字符串

import pandas as pd

# 使用字典创建一个DataFrame
data = {
    'A': ['2024-05-11', '2024-05-11', '2024-05-11'],
    'B': ['国内机票', '加油', '火车票'],
    'C': [2, 1187, 17],
    'D': ['-50.00%', '-83.21%', '183.33%'],
    'E': [2.1, 1182, 12],
    'F': ['-33.33%', '-83.18%', '100.00%'],
    'G': [1960.00, 284749.30, 2465.00],
    'H': [2182.00, 311709.68, 2419.00],
    'I': [2.2, 102, 8]
}
df = pd.DataFrame(data)

# 将数值列转换为字符串
df['C'] = df['C'].astype(str)
df['E'] = df['E'].astype(str)
df['G'] = df['G'].astype(str)
df['H'] = df['H'].astype(str)
df['I'] = df['I'].astype(str)

# 连接列
df['Result'] = df['A'] + ' ' + df['B'] + ' ' + df['C'] + ' ' + df['D'] + ' ' + df['E'] + ' ' + df['F'] + ' ' + df['G'] + ' ' + df['H'] + ' ' + df['I']

print(df['Result'])
