如何使用 python 从 pandas 数据帧中获取特定值？

Question

I'm trying to run the script below:

g20s = ['Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, Mexico, Republic of Korea, Russia, Saudi Arabia, South Africa, Turkey, United Kingdom, United States, European Union']

gdp_g20 = gdp_world.loc(gdp_world['Country Name'].isin(g20s))

But I'm gettin the error below:

TypeError: 'Series' objects are mutable, thus they cannot be hashed

Any idea of how get these values from the dataframe without having this problem?

Thanks a lot!

Answer 1

Your problem is the "(" and ")"

Try this: gdp_g20 = gdp_world[gdp_world['Country Name'].isin(g20s)]
