Question

我曾经试图像平常一样运行我的图书馆“熊猫”，但后来遇到了一个错误

.prototype

输出

import pandas as pd
df = pd.DataFrame({"city":["losangeles", "losangeles", "newyork"],
                   "beds":[3, 4, 4]})

def growth_factor(city,beds):
    if beds==3:
        if city == 'losangeles'      : return 45
        else: False
    elif beds==4:
        if city == 'losangeles'      : return 47
        elif city == 'newyork'       : return 50
        else: False
    else: False
        
The function should pass into the df and should looks like this:

df=
'city'      | 'beds' | 'growth_factor'
losangeles  |3       | 45
losangeles  |4       | 47
newyork     |4       | 50

我正在使用python 3.7

我再次安装了xlrd，但出现了相同的问题。我该如何解决？谢谢

有相同的问题，并使用了建议的修复程序 python3 -m pip install-升级xlrd 即使收到了一些警告也为我工作。
