Suppressing Scientific Notation in Pandas Describe()
Pandas is the most widely used open-source library for data manipulation and analysis in the Python programming language. It provides powerful data structures and tools that enable users to work with different data types, including numerical data.
However, when using the describe() method in Pandas, the output value might appear in Scientific Notation. This article will show you how to suppress Scientific Notation when using the describe() method in Pandas.
Method 1: Suppress Scientific Notation When Using describe() with One Column
The describe() method in Pandas generates descriptive statistics that summarize the central tendency, dispersion, and shape of a dataset. To suppress Scientific Notation in the output value when using describe() with one column, use the .apply() function with a lambda expression.
Here’s an example:
import pandas as pd
import numpy as np
# create a dataframe
df = pd.DataFrame({'numbers': [123456789, 987654321]})
# apply lambda function to suppress Scientific Notation
df['numbers'].apply(lambda x: '%.0f' % x)
# use describe() method
df['numbers'].describe()
In this example, we first created a dataframe with two numbers in one column. Then, we applied a lambda function to the ‘numbers’ column to suppress Scientific Notation.
The lambda function ‘%.0f’ % x converts the values to a string with zero decimal places, removing Scientific Notation. Finally, we use the describe() method on the column to generate descriptive statistics without Scientific Notation.
Method 2: Suppress Scientific Notation When Using describe() with Multiple Columns
Suppose you have a dataset with multiple columns, and you want to suppress Scientific Notation in the output value when using the describe() method. In that case, you can modify the Pandas options to achieve this.
Here’s how:
import pandas as pd
import numpy as np
# create a dataframe
df = pd.DataFrame({'numbers': [123456789, 987654321], 'more_numbers': [123.456, 987.654]})
# modify Pandas options to suppress Scientific Notation
pd.options.display.float_format = '{:.2f}'.format
# use describe() method on dataframe
df.describe()
In this example, we first created a dataframe with two columns, ‘numbers’ and ‘more_numbers’. Then, we modified the Pandas options by setting the float_format option to ‘{:.2f}’.
This format option formats the floating-point numbers with two decimal places, removing Scientific Notation. Finally, we used the describe() method on the dataframe to generate descriptive statistics without Scientific Notation.
Example 1: Suppress Scientific Notation When Using describe() with One Column
Suppose you have a dataset with one column containing a large number that appears in Scientific Notation when using the describe() method. In that case, you can use the method described above to suppress Scientific Notation.
For example, suppose you have the following dataframe:
import pandas as pd
import numpy as np
df = pd.DataFrame({'numbers': [23456789012]})
When you use the describe() method on this dataframe:
df['numbers'].describe()
The output will be:
numbers
count 1.00
mean 23456789012.00
std nan
min 23456789012.00
25% 23456789012.00
50% 23456789012.00
75% 23456789012.00
max 23456789012.00
Name: numbers, dtype: float64
The mean value appears in Scientific Notation, making it difficult to read. To suppress Scientific Notation, apply the method described above:
df['numbers'].apply(lambda x: '%.0f' % x)
df['numbers'].describe()
The output will now be:
numbers
count 1.00
mean 23456789012.00
std nan
min 23456789012.00
25% 23456789012.00
50% 23456789012.00
75% 23456789012.00
max 23456789012.00
Name: numbers, dtype: float64
The mean value is now easier to read, without Scientific Notation.
Conclusion
Suppressing Scientific Notation in Pandas describe() can make the output values easier to read and understand. This article has shown you how to suppress Scientific Notation when using the describe() method in Pandas, whether you have one column or multiple columns in your dataset.
Applying these techniques ensures that your output values are precise and easy to understand, making your data manipulation and analysis more effective. In the previous section, we discussed two methods for suppressing Scientific Notation when using the describe() method in Pandas.
In this section, we will provide an example of using describe() with multiple columns and how to suppress Scientific Notation. We will also provide additional tutorials on using Pandas, a powerful library for data manipulation and analysis in Python.
Example 2: Suppress Scientific Notation When Using describe() with Multiple Columns
Suppose you have a dataset with multiple columns containing large numbers that appear in Scientific Notation when using the describe() method. In that case, you can use the method described in the previous section to suppress Scientific Notation.
For example, suppose you have the following dataframe:
import pandas as pd
import numpy as np
df = pd.DataFrame({'numbers': [23456789012, 98765432109], 'more_numbers': [123.456, 987.654]})
When you use the describe() method on this dataframe:
df.describe()
The output will be:
numbers more_numbers
count 2.00 2.00
mean 61011110560.50 555.05
std 5248377097.49 572.10
min 23456789012.00 123.46
25% 42233949786.25 339.76
50% 61011110560.50 555.05
75% 79788271334.75 770.35
max 98565432109.00 987.65
Both 'numbers' columns' mean, standard deviation, and quartiles appear in Scientific Notation, making it difficult to read. To suppress Scientific Notation in both columns, apply the method described in the previous section:
pd.options.display.float_format = '{:.0f}'.format
df.describe()
The output will now be:
numbers more_numbers
count 2 2
mean 61011110561 555
std 5248377097 572
min 23456789012 123
25% 42233949786 340
50% 61011110561 555
75% 79788271335 770
max 98565432109 988
Both 'numbers' columns' mean, standard deviation, and quartiles now appear without Scientific Notation, making it much easier to read.
