string='The quick brown fox jumps over the lazy dog.'; word=scan(string,1); dowhile(lengthn(word)>0); count+1; word=scan(string, count); output; end; run; 因为要WHILE表达式必须成立才会执行DO循环,也就是说在执行 到DO WHILE语句之前,word不能为空或缺失值...

在 Python 编程中，有时我们需要将对象转换为字符串格式，以便于打印输出、日志记录或数据存储等操作。Python 提供了多种方法来将对象转换为字符串。本文将详细介绍在 Python 中将对象打印为字符串的几种常用方法，并提供示例代码帮助你理解和应用这些方法。
string='The quick brown fox jumps over the lazy dog.';word=scan(string,1);dowhile(lengthn(word)>0); count+1; word=scan(string, count); output; end; run; 因为要WHILE表达式必须成立才会执行DO循环,也就是说在执行 到DO WHILE语句之前,word不能为空或缺失值,所以代码中先对word 值赋值(word可...

substr格式:<variable=>SUBSTR(string,position<,length> )功能:替换字符串中指定的字符(将position开始,length个字符串替换为指定的字符。例如:a='KIDNAP'; substr(a,1,3)='CAT'; 结果为: CATNAP translate格式:TRANSLATE(source,to-1,from-1<,…to-n,from-n> )功能:替换字符,将‘from’替换为‘to’。
1:treat an observation as a single string of bytes by ignoring variable types and boundaries. 2:collapse consecutive repeating characters and numbers into fewer bytes. 3:contain a 28-byte overhead at the beginning of each page. 4:contain a 12-byte- or 24-byte-per-observation overhead follow...
If length is10,convert character date into the numeric date If length is7, means theDAY is missingthen impute with “01” and set imputation flag = ‘D’ If length is4, meansDAY and MONTH both are missingthen impute with01-01and set imputation flag = ‘M’. ...
但是导入到SAS里面之后，我查看导入…用substr()把年月日分别取出，并分别转换成numeric,然后用mdy()，...
