基于多条件从DataFrame中移除行的技术实现需求问询

Hey there, let's sort out your DataFrame row filtering issue properly. You want to remove rows that fit any of these three criteria:

• Text column has a string length of exactly 1
• Associated_word column is null
• Text column contains only numbers

输入数据 #

期望输出 #

修正后的代码 #

# 组合三个过滤条件，保留不满足任一条件的行
df = df[
    ~(
        (df['Text'].str.len() == 1) |
        (df['Associated_word'].isnull()) |
        (df['Text'].str.isdigit())
    )
]

代码解释 #

Let's break down how this works:

• df['Text'].str.len() == 1: Checks if the Text column's value has a string length of exactly 1
• df['Associated_word'].isnull(): Flags rows where Associated_word is empty/null
• df['Text'].str.isdigit(): Identifies rows where Text contains only numeric characters
• The | operator means "OR" — so we're targeting rows that match any of the three conditions. The ~ symbol negates the entire result, so we keep only rows that don't meet any of the rules.
