我怎么知道我的代码中的频率（如果陈述是真的）？

Question

我们假设：

for a in range(10):
  if a == 2 or a == 5:
    print (how often this condition was True) 

当然会是两个，在我的代码中我想知道我的条件何时为真，谢谢

Answer 1

count = 0 # set a variable for counting

for a in range(10): 
  if a == 2 or a == 5: # for each entry that meets the condition
    count += 1         # add 1 to count
print(count)           # 2
