Python字典到csv excel

Question

I try to get a csv from my dictionary in python.

I can create a csv file and put my dictionary in it.

The problem is that when I open the file with excel the header and the values are in one column, but I want all keys and all values in separate columns.

For example:

      column1 column2 column3        column4
row 1 "name"   "temp" "tempeinheit"  "Druck"
row 2 "test"   24      "C"             0.1 

This is the following code.

dict= [{"name" : "test", "temp" : 24, "tempeinheit": "C", "druck" : 0.1,    "druckeinheit": "Pa"},{"name" : "benni", "temp" : 24, "tempeinheit": "C", "druck" : 0.1, "druckeinheit": "Pa"}]
with open("C:\\test#\\test.csv","w",newline='') as csvfile:

writer = csv.writer(csvfile,dialect="excel-tab")

for row in dict:
    if count == 0:
        header=row.keys()
        writer.writerow(header)
        count=+1
    writer.writerow(row.values())

Update:

I just convert the Dictionary in 2 Lists. One for the keys and one for the data, and I wrote them with the writer.writerow(Data).

The other thing is, I use excel 2013 and for a new column it's not delimiter="," but the delimiter=";". so the ";" tells excel to put the data into a new column.

Thanks for the help.

Answer 1

I tried running your code and following problems were found.

• Import CSV error
• File was closed when you tried to write to it through the code.
• count variable was not initialized.

I haved added here my working code. Please let me know if you face any issue.

import csv
dict= [{"name" : "test", "temp" : 24, "tempeinheit": "C", "druck" : 0.1,    "druckeinheit": "Pa"},
    {"name" : "benni", "temp" : 24, "tempeinheit": "C", "druck" : 0}]
with open("try.csv","a") as csvfile:
    writer = csv.writer(csvfile,dialect="excel-tab")
    count = 0
    for row in dict:
        if count == 0:
            header=row.keys()
            writer.writerow(header)
            count=+1
        writer.writerow(row.values())

You can try like so with pandas:

import pandas as pd

d = [{"name" : "test", "temp" : 24, "tempeinheit": "C", "druck" : 0.1,    "druckeinheit": "Pa"},
     {"name" : "benni", "temp" : 24, "tempeinheit": "C", "druck" : 0.1, "druckeinheit": "Pa"}] 

df = pd.DataFrame(d)

df = df[['name', 'temp', 'tempeinheit', 'druck','druckeinheit']]
df.to_csv('filename')
