7 Python Tips and Tricks You Probably Don’t Know

Most Common and Notorious Python Tips for Pro Codding

Python is notorious and amazing but do you know some time-saving Tips for Python that will improve your coding style in Python. In this article, we will look over the 7 Tips and tricks in Python that you Probably don’t know. So bookmark the article and let's dive into it.

1. Count the Frequency

Now you don’t need to use loops to count the frequency of every element in the list. You can do it with Python built-in module counter. Moreover, you can also count for specific elements too. Check the example code below.

# Count Frequency

import collections

lst = [1,2,3,2,2,4,4,4,5,6,7,7,7,5,3]
counter=collections.Counter(lst)

print(counter)

#output
# Counter({2: 3, 4: 3, 7: 3, 3: 2, 5: 2, 1: 1, 6: 1})

2. Fast way to Format String

You probably use the format() function to format your string or % method. But do you know there is a faster way to format your string without writing these lengthy methods? Check out the example code below:

# Fast way to Format String

w1 = "something"
w2 = "Daily"

data = f"Code is {w1} we should do {w2}"

print(data) # Code is something we should do Daily

3. Read CSV without Pandas

Now you no longer need Pandas module to read and write CSV. You can use the Python built-in module to do the same stuff as shown below:

# CSV Reading

import csv

with open('test.csv', 'r') as file:
    r = csv.reader(file)
    for row in r:
        print(row)

4. Get File Name From Path

This awesome tip will help you get the file name from the path. This will be handy for someone who needs to extract the name of the file from a full path. Check out the example code below:

# Get file name from Path

import os

filepath =  "/path/to/file.txt"

filename = os.path.basename(filepath)

print(filename) # file.txt

# file name without extension

print(filename.split(".")[0]) # file

5. Magic of Regular Expression

Regular expression is an awesome tip for extracting, matching, and searching a specific string in Text data. Below I mention an example code for extracting phone numbers from raw text data:

# Magic of Regular Expression

import re

# example 1

phn = "jajdasko;askj9234989835kfpwek"

r = re.findall("[0-9]", phn)

print("".join(r)) # 0234989835

6. Hidden Functions of Print

Do you know the Python print() method had some arguments functions too? In the below example code I mention two of the common Python argument functions you must see.

# Hidden Python Func

# hidden 1

print("hello", end=" ")
print("world")

#output:
#hello world

#hidden 2

print("Python", "is", "somthing", "different", sep="#")

#output
#Python#is#somthing#different

7. Iterate Pair of List

This simple tip and trick will help you iterate two pairs of lists at the same time. Check out the below code:

# iterating pair of String

lst1 = ['a', 'b', 'c', 'd']
lst2 = ['1', '2', '3', '4']

for x, y in zip(lst1, lst2):
    print(x, y)

# output
# a 1
# b 2
# c 3
# d 4
