我试图格式化存储为浮点数的“ year”的输出格式，四舍五入到小数点后0位，并删除数据框信息。

# Display earliest,most recent,and most common year of birth
print('Earliest year of birth:')
min_yob = df.birth_year.min()
print(round(min_yob))

print('Max year of birth: ')
max_yob = df.birth_year.max()
print(round(max_yob))

print('Most common year of birth: ')
mod_yob = df.birth_year.mode()
print(round(mod_yob))

我为此获得的输出如下：

Earliest year of birth:
1899
Max year of birth: 
2016
Most common year of birth: 
0    1989.0
dtype: float64

如果我将mod_yob转换为int，它将正确显示，但是我不确定为什么round（）在这里不起作用。

 Most common year of birth: 
 1989

也许我会以错误的方式进行操作。
