该计划是采取“千分之三”,并在错误的地方分离
第二栏应该是:财富中值:“227891”
第三栏:平均财富:“564653”
第四栏:人口:“6866”
最后,程序收到一个错误,因为总数超过了列数
我的代码:
import matplotlib.pyplot as plt
separate = ','
with open('wealth-per-country.csv', 'r') as arq:
for line_number, content in enumerate(arq):
if line_number:
column = content.strip().split(separate)
print(f"Country: {column[0]}, \nMedian_Wealth: {column[1]}, \nMean_Wealth: {column[2]}, \nPopulation: {column[3]}")
