如果没有合理的分隔策略,合并和拆分数据可能会导致信息丢失或错误解析,从而影响最终的数据分析结果。例如,处理一份包含用户信息的 CSV 文件,若姓名、地址等字段使用了多个不同分隔符(如逗号、分号、空格等),若不加以处理,将导致数据解析困难。 业务影响分析: 数据解析错误可能导致业务决策失误。 影响后续数据分析模型的构建和训练。

This article will show you how to split a string at a given delimiter in Bash/Shell scripts and show some examples. Splitting strings is a handy function to have available when crafting your scripts. CSV (Comma Separated Values) is a common format in which data is made available online, wh...
6. When the Input Is a Multi-Line CSV File So far, we’ve explored how to parse and store the single-line CSV input.If we need to handle a multi-line CSV file, we can extend the solutions with awhileloop. Let’s see an example: ...

接下来,我们定义了一个splitWithMultipleSeparators函数,该函数接受一个字符串和一个分隔符切片作为参数。在该函数中,我们定义了一个匿名函数separatorFunc作为分隔符函数。该函数会遍历分隔符切片,检查每个字符是否为分隔符。如果是分隔符,则返回true,否则返回false。 最后,我们使用strings.FieldsFunc函数将字符串按...
