Python | numpy.lookfor() method Last Updated : 03 Oct, 2019 Comments Improve Suggest changes Like Article Like Report With the help of numpy.lookfor() method, we can get the information about the module in the numpy by using numpy.lookfor() method. Syntax : numpy.lookfor(module_name) Return : Return the information about the module. Example #1 : In this example we can see that by using numpy.lookfor() method, we are able to get the information about the module. Python3 1=1 # import numpy import numpy as np # using numpy.lookfor() method print(np.lookfor("isin")) Output : Search results for 'isin' ------------------------- numpy.isinf Test element-wise for positive or negative infinity. numpy.compat.is_pathlib_path Check whether obj is a pathlib.Path object. numpy.isin Calculates `element in test_elements`, broadcasting over `element` only. Example #2 : Python3 1=1 # import numpy import numpy as np # using numpy.lookfor() method print(np.lookfor("isdigit")) Output : Search results for 'isdigit' ------------------------- numpy.bytes0.isdigit B.isdigit() -> bool numpy.str0.isdigit S.isdigit() -> bool numpy.chararray chararray(shape, itemsize=1, unicode=False, buffer=None, offset=0, numpy.char.isdigit Returns true for each element if all characters in the string are numpy.chararray.isdigit Returns true for each element if all characters in the string are None Comment More infoAdvertise with us Next Article Python | numpy.lookfor() method J Jitender_1998 Follow Improve Article Tags : Technical Scripter Python Python-numpy Practice Tags : python Similar Reads Python | numpy.isin() method With the help of numpy.isin() method, we can see that one array having values are checked in a different numpy array having different elements with different sizes. Syntax : numpy.isin(target_array, list) Return : Return boolean array having same size as of target_array. Example #1 : In this example 1 min read Python | Numpy np.char.endswith() method With the help of np.char.endswith() method, we can get the boolean array when values ends with a particular character passed in np.char.endswith() method. Syntax : np.char.endswith() Return : Return the boolean array when values ends with a value. Example #1 : In this example we can see that by usin 1 min read numpy.find() in Python numpy.core.defchararray.find(arr, substring, start=0, end=None): Finds the lowest index of the sub-string in the specified range. Parameters: arr : array-like or string to be searched. substring : substring to search for. start, end : [int, optional] Range to search in. Returns : An integer array wi 1 min read numpy.nonzero() in Python numpy.nonzero()function is used to Compute the indices of the elements that are non-zero. It returns a tuple of arrays, one for each dimension of arr, containing the indices of the non-zero elements in that dimension. The corresponding non-zero values in the array can be obtained with arr[nonzero(ar 2 min read numpy.fmin() in Python numpy.fmin() function is used to compute element-wise minimum of array elements. This function compare two arrays and returns a new array containing the element-wise minima. If one of the elements being compared is a NaN, then the non-nan element is returned. If both elements are NaNs then the first 2 min read Like
