🧩 Master .format() for strings

Published 6 days ago • 1 min read

Welcome back to Pandas Daily! Today, master Python in 7 snippets.

Yesterday, we explored "f-strings", a MUST KNOW modern and clean way to insert text and format strings. However, you would also come across .format() , a previous version still used by many (for sure by my old boss :/ ).

Note: Do go through the pervious post to better understand .format()

💥 Pass values using {}

  In:

  name = "Sam"

  # put the value into { }

  print("Hello, {}".format(name))

  Out: Hello, Sam

🔀 Multiple curlies {} to add multiple values

  In:

  name = "Sam"

  marks = 88

  # values fill the { } in order

  print("{} scored {} marks".format(name, marks))

  Out: Sam scored 88 marks

🧭 Control which value needs to be placed where

  In:

  # {1} uses the second value, {0} uses the first

  print("{1} comes after {0}".format("A", "B"))

  Out: B comes after A

🪶 Define variable directly in .format()

  In:

  # use labels inside { } and pass values by label

  print("Name: {n}, Age: {a}".format(n="Sam", a=25))

  Out: Name: Sam, Age: 25

🕹️ Pad numbers with zeros

  In:

  num = 5

  # width 3, pad with zeros on the left

  print("{:03}".format(num))

  Out: 005

🤑 Add comma for large numbers

  In:

  num = 1000000

  print("{:,}".format(num))

  Out: 1,000,000

💡 Align text left, right and center

  In:

  print("{:<5}".format(word))  # left

  print("{:>5}".format(word))  # right

  print("{:^5}".format(word))  # center

  Out:

📜 I can make data readable in Python

Welcome back to Pandas Daily! Your daily 5-minute boost to becoming confident in Python. We all agree that dashboards, emails, logs should read like English. Meaning 1.2 million beats 1234567 and 3.1M is more readable than 3145728. Stakeholders scan - and they get pissed if they have to parse messy numbers 😭😭 So today, we explore a third-party humanize library. Format numbers, file sizes, and dates/times into human-readable text. Mini exercise at the end. 🥇 Ready, Get, Set, Go! Install and...

⁉️ Not many know that Python can analyze emojis 😀

Welcome back to Pandas Daily! Your daily 5-minute boost to becoming confident in Python. Amazon reviews, chats and social media text (posts, comments, stories etc) are full of emojis 🔥🔥 Great for expression! But give a hard time for text interpretation (Amazon, Meta would be going crazy). That is where Python's demoji library comes in. From a given text you can: Extract emojis Remove them if needed Replace with textual meaning Understand sentiment and what not... Let's begin!! Install demoji...

🤫 Secret data types smarter than lists, dicts

Welcome back to Pandas Daily! Your daily 5-minute boost to becoming confident in Python. We all know Python’s basic container data types — lists, dictionaries, tuples, sets. "Container" is just a data type that holds multiple items instead of single values. However, many times basics are not enough. Like if you want count of different items in the list you will run a loop like below. In: fruits = ["apple", "banana", "apple", "cherry"] counts = {} for item in fruits: counts[item] =...
