Picture of file所以，我正在制作这个程序，你拿一个文件并将其分解并取出你需要的特定部分，然后将这些值添加到字典中，然后将该字典附加到一个列表中。执行此操作后，您将搜索您拥有的词典列表，并根据用户提供的信息提取某些值。到目前为止，我已经完成了所有工作，但现在我必须将字典列表中的所有内容都设为小写，但字典列表中包含不同的值类型，我不知道如何去做。
这是我的代码：
#!/usr/bin/env python3
import os.path
def get_file_name(file_name):
if os.path.exists(file_name):
return file_name
else:
file_name = input('Please enter a file name: ')
get_file_name(file_name)
def search_counties(new_list):
c = [line.strip(',') for line in new_list]
texts = [[word.lower() for word in text.split(',')] for text in c]
print(c)
county = input('Search: ')
county.lower()
while county not in ['q', 'quit']:
for row in new_list:
county_name, county_count, county_percent, county_median = row.split(',')
if county == county_name:
pass
'''
while that search term is not q or quit enter a loop
1. iterate over your counties parameter to see if any of the county's names match the search term
** You may need to convert your search term to lowercase and compare it to the county name converted to lowercase
2. if you find a match then call print_county and pass it your county dict
3. ask the user for another search term (gives the user a chance to search again or q or quit to exit)

def print_highest_data(counties):
# This function is complete
# since we sorted our list of counties in main() all we have to do here is call print_county and pass it the last county dict in our list
print_county(counties[-1])
def print_lowest_data(counties):
print_county(counties[0])
# same as above, except we call print_county and pass it the first county dict in our list
def print_county(county):
# This function is complete
# if you use different keys in your dicts then you'll need to change them below
print('Name: %s' % county['name'])
print('Percentage: %.2f%%' % county['percent'])
print('Children in Poverty: {:,}'.format(county['count']))
print('Household Income: ${:,}'.format(county['income']))
print()
def main():
new_list=[]
file_name = input('Please enter a file name: ')
file = get_file_name(file_name)
file = open(file_name, 'r')

for row in file:
if first_line == True:
first_line = False
continue
dictionary={}
dictionary['name']= str(row[193:238])

print_lowest_data(new_list)
search_counties(new_list)
# prompt for the filename
# check to make sure file exists, if it doesn't prompt again
# create an empty list to contain all of the contains
'''
iterate over each line in the file (**you may need to skip the first line if it contains a header)
For each line parse out the children count, percentage of children in poverty, median income, and county name
**For help parsing, view the census.gov page (http://www.census.gov//did/www/saipe/data/statecounty/data/2014.html)
Add those four values to a dict (this dict will represent the county)
append that dict to your list
'''
'''
once you leave your for loop sort the counties by percentage
**see the lab instructions for guidance on how to sort the dict by a particular value
