熊猫不是进口的吗？'NameError: 全局名称 'pandas' 未定义'

Question

我在这里遇到了一些错误，但我认为这是由于熊猫未导入，因为它变灰了。如果这是问题，我将如何解决这个问题？

C:\Anaconda\python.exe C:/Users/nickd/Documents/SKLEARN-STOCKS/stock-mach.py​​ Traceback（最近一次调用最后一次）：文件“C:/Users/nickd/Documents/SKLEARN-STOCKS/stock -mach.py​​”，第 38 行，在 Key_Stats() 文件“C:/Users/nickd/Documents/SKLEARN-STOCKS/stock-mach.py​​”，第 12 行，在 Key_Stats 中 df = pandas.DataFrame(columns = [' Date','Unix','Ticker','DE Ratio']) NameError: 全局名称 'pandas' 未定义

import pandas as pd

    save = gather.replace(' ','').replace(')','').replace('(','').replace('/',''+('.csv')
    print(save)
    df.to_csv(save)

Answer 1

您已将其导入为

import pandas as pd

并打电话

#pandas
df = pandas.DataFrame(columns = ['Date','Unix','Ticker','DE Ratio'])

你可以改变

• import pandas as pd到import pandas或
• df = pandas.DataFrame(columns = ['Date','Unix','Ticker','DE Ratio'])到df = pd.DataFrame(columns = ['Date','Unix','Ticker','DE Ratio'])。

编辑：

错误是由于缺少 )

save = gather.replace(' ','').replace(')','').replace('(','').replace('/',''+('.csv'))
