检查Python中条件字典中的浮点值

Question

我有一个字典，如图所示，我想知道我应该如何编写一些东西来检查每个键的每个值，并检查它们是否符合某个特定的条件像8以上的值等。

的值是浮子和有每个区域的字典值的多个值。

def main(): #defining main function 
    magList = [] #magnitude list of all together 
    regionList = [] #creating list to hold region names 
    wholeList = [] 
    combinedList = [] 

    with open("earthquakes.txt", "r") as eqList: #opens earthquake text file and gets the magnitudes 
     eqList.readline() 
     for line in eqList: 
      line = line.split() 
      magList.append(float(line[1])) #appends magnitude as float values in list 

    with open("earthquakes.txt", "r") as eqList2: #open file 2nd time for gathering the region name only 
      eqList2.readline() 
      for line in eqList2: 
       line = line.split() 
       line = line[0:7] + [" ".join(line[7:])] #takes whole line info and adds to list 
       wholeList.append(line) 

    greatMag = [] #creating lists for different category magnitudes 
    majorMag = [] 
    strongMag = [] 
    moderateMag = [] 

    for x in magList: #conditions for seperating magnitude 
     if x >= 8: 
      greatMag.append(x) 
     elif 7 <= x <= 7.9: 
      majorMag.append(x) 
     elif 6 <= x <= 6.9: 
      strongMag.append(x) 
     elif 5 <= x <= 5.9: 
      moderateMag.append(x) 

    for line in wholeList: #takes only magnitude and region name from whole list 
     combinedList.append([line[7], line[1]]) 

    infoDict = {} #creates dictionary  
    for key, val in combinedList: #makes one key per region and adds all values corresponding to the region 
     infoDict.setdefault(key, []).append(val) 
    print(infoDict) 

    for k, v in infoDict.items(): 
     for i in v: 
      if i >= 8: 
       print("Great Magnitude:", i) 
       pass 

if __name__ == "__main__": #runs main function 
    main()

for k,v in d.items(): # iterate through key, value of dict 'd' 
    for i in v: # iterate to dict value which is a list 
    if i > 8: # your condition 
     # do something here 
     pass
