Here's the error: for j in range (len(rotlati)):

TypeError: object of type 'float' has no len()

I have seen many other posts but I haven't found the solution yet. I'm a bit confused. Please comment if you know what's going on here.

The code is:

m = 22
rlati = numpy.zeros(m)
n = 22
rlongi = numpy.zeros(n)

v = numpy.ndarray((2,),float)

for j in range (len(lati)):
LA = lati[j]
    rlati[j] = LA - latiref

    for i in range (len(longi)):
        LO = longi[i]

    rlongi[i] = LO - longiref

    v[0] = rlati[j]
    v[1] = rlongi[i]

    vv = numpy.matrix(v)
    #transpose of vv as vv.T
    vv = vv.T

    #proper rotation
    vn = R*vv

    #define how many decimals
    vn = numpy.around(vn, decimals =2)

    # rotation of the second column (lati) and third line (longi)
        rotlati = float(vn[0])
    rotlongi = float(vn[1])

s = 22
latidef = numpy.zeros(s)
p = 22
longidef = numpy.zeros(p)

for j in range (len(rotlati)):
RLA = rotlati[j]

    latidef[j] = RLA + latiref

for i in range (len(rotlongi)):
        RLO = rotlongi[i]

    longidef[i]= RLO + longiref

    RLADEF = latidef[j]
    RLODEF = longidef[i]

    return RLADEF, RLODEF

The error is exactly what is says it is. rotlati is a float. You cannot take the len() of a float. Looking at your code, it looks as if you might have meant to create lists called rotlati and rotlongi and append to them on each iteration of your range(len(lati)) loop. Instead you're currently just overwriting the same two floating-point variables on every iteration.

The len argument may be a sequence (string, tuple or list) or a mapping (dictionary). https://docs.python.org/2/library/functions.html#len

Before calling the len function, you should verify if the argument is one of this type. You can call the method isinstance() to verify it. Take a look on how to use it. https://docs.python.org/2/library/functions.html#isinstance

Object of type CcEvent is not JSON serializable. � Issue #284, I was downloading all Audits data and when trying to serialize to a JSON file I got a TypeError: Object of type CcEvent is not JSON serializable. Any idea what� TypeError: object of type ‘int’ has no len () In python, the error “TypeError: object of type ‘int’ has no len ()” occurs when the length function is invoked on objects that does not support the length function. The length function is supported by iterable objects such as list, tuple, dictionary and string. The length function is used to find the length of the string or the number of objects in a structured objects such as list, tuple and dictionary.

Another scenario i got the same error, while saving file.

You may also check the name of the sheet is int or float. Convert that to string.

  • Well, rotlati is a float and does not support len(). What don't you understand?
