**[Julia](https://www.educative.io/answers/julia-language)** is a powerful programming language for complex computational analysis in machine learning and data science.

**DataFrames** are 2D data structures that help organize data into a table with distinct rows and columns.

There are two ways to obtain the number of rows in a DataFrame in Julia.

* Using the `nrow()` function

* Using the `size()` function
##
## Using the `nrow()` function
The `nrow()` function obtains the total number of rows present.


## Syntax
```
nrow(dataframe)
```
## Code




using DataFrames
df = DataFrame(student_id=[1,2,3,4,5], 
                name = ["Amy","Jane","John","Nancy","Peter"],
                marks=[50,60,70,98,30], 
                age=[15,20,18,19,15])

println(nrow(df))

julia

## Explanation
* **Line 1:** Imports `DataFrames` for use.
* **Lines 2–5:** Creates a DataFrame with five rows.
* **Line 7:** Prints out the number of rows in the DataFrame.

## Using the `size()` function
The `size()` function helps obtain a dataset's number of columns and rows. To get the number of rows, specify `1` inside or outside the function, as shown in the syntax below.

## Syntax
```
size(dataframe,1)
size(dataframe)[1]
```

## Code


using DataFrames
df = DataFrame(student_id=[1,2,3,4,5], 
                name = ["Amy","Jane","John","Nancy","Peter"],
                marks=[50,60,70,98,30], 
                age=[15,20,18,19,15])

println(size(df,1))
println(size(df)[1])

## Explanation
* **Lines 1–5:** Import the necessary packages and create a DataFrame.
* **Lines 7–8:** Print out the number of rows in a DataFrame using the `size()` function.
