Overview:
- Strings are ubiquitous in computing world. Though there is no separate type called “character” in Python, strings are supported extensively.
- Strings are texts of arbitrary length. Python strings are immutable.
- In Python the strings are Unicode.
- While the pandas DataFrame supports exporting its contents to several formats like CSV, Excel, HDF5 and others, it also supports exporting of a DataFrame object into a string.
- The method to_string() of the DataFrame class exports the contents of a DataFrame into a Python string.
Example:
|
# Example Python program that exports the contents of a DataFrame into a Python string import pandas as pds
# A dictionary of mappings mapping = {"S1":(51, 33, 21, 66), "S2":(50, 32, 26, 40), "S3":(24, 65, 39, 44), "S4":(67, 23, 71, 37)}
# Construct a pandas DataFrame df = pds.DataFrame(data=mapping);
# Print the pandas DataFrame as a Python string dataFrameAsString = df.to_string(); print("Contents of the pandas DataFrame as Python string:"); print(dataFrameAsString); print(type(dataFrameAsString)); |
Output:
|
Contents of the pandas DataFrame as Python string: S1 S2 S3 S4 0 51 50 24 67 1 33 32 65 23 2 21 26 39 71 3 66 40 44 37 <class 'str'> |
