间距
【Spacing】
除非用引号括起来,否则变量键和值周围的前后空白字符会被忽略。
【Leading and trailing whitespace characters around variable keys and values are ignored unless they are enclosed within quotes.】
例如:
【For example:】
MY_VAR_A = my variable a
MY_VAR_B = ' my variable b ' 将被视为与以下情况相同:
【will be treated identically to:】
MY_VAR_A = my variable a
MY_VAR_B = ' my variable b '
