return 0; } 输出结果为: python The integer value of 123 is 123 需要注意的是,atoi函数只能将合法的整数字符串转换为整数类型,如果字符串中包含非数字字符,则转换结果可能不正确。此外,atoi函数只能处理整数类型的转换,如果需要将其他数据类型转换为字符串,可以使用其他的类型转换函数或字符串拼接函数。©...

We cast the variable x (integer) and the variable y (float) to a string using the str() function. What if we have text that we want to store as number? We will have to cast again. a ="135.31421" b ="133.1112223" c =float(a) +float(b) ...

This is why I've always wished JS supported splitting a string into multiple adjacent literals as in C, e.g. "a" "b" compiles down to "ab" 👍 1 Contributor Josh-Cena commented May 6, 2023 "a" "b" is so error prone—I've seen many Python programmers complaining that missing...
So, instead of asking whether SQLAlchemy hasn't failed with error as desccribed above, I would like to set a better question: How come type affinity of malformed string that should be a integer, is actually a TEXT AND is accepted by SQLite? Why doesn't it throw error if it's clear...
