python-3.x - 将 ititems-Result 存储在数据框中

Question

目标： 在我的 nfl 团队数据框 (df_teams) 中添加一列 ('Team_url')，其中包含每个团队的网站 URL。

问题： 如果我打印 url，它工作得很好。如果我尝试将其存储到 df_teams['Team_url']，它只会存储 iteritems 的最后一个结果。

数据：

df_teams['Team_web']

0            Arizona-Cardinals
1                Chicago-Bears
2            Green-Bay-Packers
3              New-York-Giants
4                Detroit-Lions
.
.
.
31              Houston-Texans

代码：

for i, j in df_teams['Team_web'].iteritems():
    url_1 = "https://www.nfl.com/teams/{0}/roster".format(j)
    df_teams['Team_url'] = url_1

打印：

print(url_1):

https://www.nfl. com/teams/Arizona-Cardinals/roster
https://www.nfl. com/teams/Chicago-Bears/roster
.
.
.
https://www.nfl.com/teams/Houston-Texans/roster

print(df_teams['Team_url'])

0     https://www.nfl.com/teams/Houston-Texans/roster
1     https://www.nfl.com/teams/Houston-Texans/roster
2     https://www.nfl.com/teams/Houston-Texans/roster

问题： 如何将 url_1 打印的内容存储在数据框列中？

Answer 1

df['Team_url'] = 'https://www.nfl.com/teams/' + df['Team_web'] + '/roster'
