[英]How to check if a float value is within a certain range and has a given number of decimal digits?
[英]Python - how to check if the value is within given range of float/integer?
为什么这不起作用?
reflace=0
input = "55,1,1,1".split(",")
# Now find the first field from comma
input[reflace] = round( float( input[reflace] ) , 2) + 0.01
ranges = [(-1,1)]
if any(lower <= input[reflace] <= upper for (lower, upper) in ranges):
print "+ " + input
不打印
将字符串的名称从input
更改为其他名称。 我正在使用inputData
。
reflace=0
inputData = "55,1,1,1".split(",")
# Now find the first field from comma
inputData[reflace] = round( float( inputData[reflace] ) , 2) + 0.01
print inputData[reflace] ### Will print 55.01
ranges = [(-1,1)]
if any(lower <= inputData[reflace] <= upper for (lower, upper) in ranges):
print "+ " + inputData
因此,您正在检查55.01是否在-1,1的范围内。这是不正确的。 这就是为什么什么都没打印出来的原因。
