Talk to a mentorSame analysis, two languages: code side by side
Group a dataset by category and compute the average — see how Python and R differ.
import pandas as pd df = pd.read_csv("sales.csv") summary = ( df.groupby("category", as_index=False) .agg( avg_sales=("sales", "mean"), total_orders=("order_id", "count"), ) .sort_values("avg_sales", ascending=False) ) print(summary.head())
Python uses Pandas with method chaining: groupby, agg, sort_values. Readable, explicit, and works well inside scripts, notebooks and production pipelines.
library(dplyr) library(readr) df <- read_csv("sales.csv") summary <- df |> group_by(category) |> summarise( avg_sales = mean(sales, na.rm = TRUE), total_orders = n() ) |> arrange(desc(avg_sales)) print(head(summary))
R uses the tidyverse pipe |> to chain verbs: group_by, summarise, arrange. Very expressive and natural for analysts.

Frequently asked questions: Python vs R for Data Science
Answers to what freshers and analysts ask us most.
Which pays more in India in 2026: Python or R for Data Science?
Pay depends far more on your skills, projects and company than on the language alone. Both are paid in a similar band — indicatively ₹4–8 LPA for freshers and ₹8–18 LPA with 2–4 years of experience in data science roles. Python has far more openings overall because it is used across data science, ML, backend and automation. R roles are more concentrated in analytics-heavy industries like pharma, finance and research, where strong R + statistics skills can pay very well.
Is R easier to learn than Python for a beginner?
It depends on your background. R is designed for statistics and data analysis, so if your goal is pure data exploration and statistical modelling, R's syntax and built-in functions feel natural. Python is a general-purpose language with a gentler, more consistent syntax that most beginners find easier to read. For someone new to programming, Python is usually the easier start; for someone with a statistics background, R can feel very intuitive.
What is common between Python and R for Data Science?
Both are open-source languages widely used in data science. Both have strong libraries for data manipulation, visualization, statistics and machine learning. Both support Jupyter notebooks, can connect to databases and APIs, and are used in production and research. Many data teams use both — Python for engineering and ML, R for statistical analysis and reporting.
Can I switch from R to Python later in my career?
Yes. Data science concepts — data cleaning, EDA, statistics, modelling — carry over. The main effort is learning Python syntax and its ecosystem (Pandas, NumPy, scikit-learn, Matplotlib). An R user with strong statistics fundamentals can usually become productive in Python within 4–8 weeks of focused practice.
Which one should a fresher choose for placements?
For placements in India, Python is the clear choice — it has vastly more data science, ML and analyst openings, and it is also useful for backend and automation roles. R is valuable if you are targeting analytics-heavy roles in pharma, finance, market research or academia. Many learners start with Python and add R later for statistical depth.
Is Python better than R for machine learning?
For most machine learning work, Python is the stronger choice. It has scikit-learn, TensorFlow, PyTorch, XGBoost and a massive ecosystem for ML engineering and deployment. R has solid ML packages (caret, tidymodels, randomForest), but production ML pipelines and deep learning are overwhelmingly Python-first in 2026.
How long does it take to become job-ready in Python or R for Data Science?
With regular practice, most learners need 5–7 months for a data science role: language fundamentals, data manipulation, statistics, visualization, ML basics, SQL, 2–3 portfolio projects and interview prep. Prior statistics or programming experience shortens this. Python learners often spend slightly more time on ML; R learners often spend more time on general programming.
