Question

这是我脚本的一个非常小的版本。我改变它来测试if语句。布尔值是False，那是对的！当我更改行的值时，highRisk始终会收到正确的值（True / False）。但即使使用正确的highRisk值，结果也始终是＆＃34; ok＆＃34;。有谁能解释我为什么？

row = 5

riskHigh = (reasons.iloc[row,1:2] == "high").bool

if riskHigh:
    print "ok"
else:
    print "oops"

结果：

In [60]: row = 5
    ...: riskHigh = (reasons.iloc[row,1:2] == "high").bool
    ...: 
    ...: if riskHigh:
    ...:     print "ok"
    ...: else:
    ...:     print "oops"
    ...: 
    ...: 
ok

In [61]: print riskHigh
<bound method Series.bool of Risk_Rating    False
Name: 5, dtype: bool

Answer 1

正如印刷品所说，riskHigh是一种方法。你应该调用方法：

riskHigh = (reasons.iloc[row,1:2] == "high").bool()

Python IF语句始终返回True
