基于舍入条件从数据帧中排除行

Question

当四舍五入到2位小数的列长度等于列长度时，如何从df中排除行？你知道吗

import pandas as pd
d = {'legs': [2.051, 4.07, 8.298, 0.234],'wings': [2.05, 4.179,8.903,0.294],'seen': ['five', 'one', 'two', 'four']}
df = pd.DataFrame(data=d)

print(df)

在这种情况下，它应该下降第一行，当圆柱腿2.05它等于2.05对柱翅膀。你知道吗

Answer 1

这是我的解决方案，让我知道这是否适合你。你知道吗

d = {'legs': [2.051, 4.07, 8.298, 0.234],'wings': [2.05, 4.179,8.903,0.294],'seen': ['five', 'one', 'two', 'four']} #dictionary
df = pd.DataFrame(data=d).round(2)#creating the dataframe and also rounding it to 2 decimal

原始数据帧的输出：

   legs    wings    seen
0   2.05    2.05    five
1   4.07    4.18    one
2   8.30    8.90    two
3   0.23    0.29    four

df_new = df[df['legs'] != df['wings']] #this will apply the condition and assign it to new dataframe or anything else.
df_new

输出：

    legs    wings   seen
1   4.07    4.18    one
2   8.30    8.90    two
3   0.23    0.29    four
