Python: Write (without writing separate lines between rows) and read a CSV file with specified delimiter
Python module: Exercise-6 with Solution
Write a Python program to write (without writing separate lines between rows) and read a CSV file with a specified delimiter. Use csv.reader
Sample Solution:
Python Code:
import csv
fw = open("test.csv", "w", newline='')
writer = csv.writer(fw, delimiter = ",")
writer.writerow(["a","b","c"])
writer.writerow(["d","e","f"])
writer.writerow(["g","h","i"])
fw.close()
fr = open("test.csv", "r")
csv = csv.reader(fr, delimiter = ",")
for row in csv:
print(row)
fr.close()
Sample Output:
['a', 'b', 'c'] ['d', 'e', 'f'] ['g', 'h', 'i']

Python: Tips of the Day
Inverts a dictionary with non-unique hashable values:
Example:
def tips_collect_dictionary(obj):
inv_obj = {}
for key, value in obj.items():
inv_obj.setdefault(value, list()).append(key)
return inv_obj
ages = {
"Owen": 25,
"Jhon": 25,
"Pepe": 15,
}
print(tips_collect_dictionary(ages))
Output:
{25: ['Owen', 'Jhon'], 15: ['Pepe']}
