from DFCompare import DFCompare

a = """Name,Value
Felix,123
Joyce,231213

Tat,
"""

b = """Name,Value
Felix,1234

"""

df_a = pd.read_csv(StringIO(a), sep=',')
df_b = pd.read_csv(StringIO(b), sep=',')

compare_a = DFCompare(df_a)

# No. of rows
compare_a.compare_rows(df_b)
# Output:
# base    5
# data    4
# dtype: int64

# No. of columns
compare_a.compare_cols(df_b)
# Output:
# base      2
# data      2
# common    2
# dtype: int64

# Data types
compare_a.compare_dtypes(df_b)
# Output:
#   Column    dtype
#              base     data match
# 0   Name   object   object  True
# 1  Value  float64  float64  True

# Base data that is not in the data to be compared
compare_a.rows_not_in(df_b)
# Output:
#     Name   Value
# 0  Felix   123.0
