爲什麼返回值只有南？

Question

這裏是我的代碼，我嘗試運行，但我沒有在輸出端獲得的值，

import numpy 
import geocoder 

data = numpy.loadtxt(fname = 'Flywheel_SF.csv', delimiter = ',', dtype = numpy.ndarray) 
start = list() 
end = list() 
z_code = numpy.zeros((101,2)) 

for i in range(1,101): 
    s = geocoder.google([data[i,4], data[i,5]], method='reverse') 
    e = geocoder.google([data[i,6], data[i,7]], method='reverse') 
    start.append(s.postal) 
    end.append(e.postal) 
    z_code[i,0] = s.postal 
    z_code[i,1] = e.postal 


zipcode = [start, end] 

print(z_code) 

這裏是我得到的輸出，

[[ 0. 0.] 
[ nan nan] 
[ nan nan] 
[ nan nan] 
[ nan nan] 
.... 
.... 
[ nan nan] 
[ nan nan] 
[ nan nan] 
[ nan nan] 
[ nan nan] 
[ nan nan]] 

輸出應該是這樣的，這些是從經度和經度轉換的郵編

[[  0.  0.] 
[ 94105. 94103.] 
[ 94133. 94108.] 
[ 94133. 94133.] 
[ 94114. 94122.] 
[ 94104. 94128.] 
[ 94128. 94066.] 
...... 
...... 
[ 94128. 94066.] 
[ 94118. 94116.] 
[ 94109. 94102.]] 

請幫助，提前謝謝！

一個可能的原因是您發送到google api的請求數量。 你可以每天只能撥打2500次電話。
