conditional expression: if 在for后面, if修饰整个语句 never_login_users = [user for user in new_shared_user_ids if is_user_never_login(user)] ternary operator: if 在 for前面, 只修饰 最前面的user never_login_users = [user if is_user_never_login(user) else '' for user in new_shared_...
Ternary OperatorThe ternary operator in Python is a concise way to write conditional expressions in a single line.x = 10result = “x is greater than 5” if x > 5 else “x is less than or equal to 5” # CombinedIf-elseprint(result)...
The ternary operator works just like in other languages.x = condition ? true_value : false_value The only exception is that nested ternary operators are forbidden to improve legibility. If your branching needs are more complex than this you need to write an if/else construct....
• What is the idiomatic Go equivalent of C's ternary operator? • bash "if [ false ];" returns true instead of false -- why? • One-line list comprehension: if-else variants • Kotlin Ternary Conditional Operator • Conditional statement in a one line lambda function in python?
I'd like some kind of conditional operation added to expression syntax. This can be an actual ternary operator (?:) or a built-in function (e.g.,if(<condition>, <true-value>, <false-value>)). Additional information There is a workaround: using shell scripts to evaluate the condition,...

x < 0) v@Cd = {0,1,0}; // to execute more operations, we need to use a block of code in {} brackets else { v@Cd = {0,0,1}; v@P += v@N; } // it is also possible to use conditional (ternary) operator with the following syntax // (condition) ? true : false v@...
