map(function, iterable, ...):将函数对象依次作用于表的每一个元素。 max(iterable, *[, key, default]):返回可迭代对象中的最大值。 memoryview(obj):根据obj生成相应的memoryview对象。 min(iterable, *[, key, default]):返回可迭代对象中的最小值。 next(
3. eval()仅支持有效的表达式求值并返回计算结果 2.21 filter(function, iterable): 类似表达式的过滤。比列表推导式省内存 1. 如果function不是None,等效于生成器表达式,比列表推导式省内存 2. 如果function是None,等效于列表推导式 f = filter(None,shares) # 函数为None,类似列表推导式,循环打印出每一个值 p...
