在python2.7中搜索二维数组中是否有字符在该位置

def search_char_in_2d_array(array, target_char):
    found = False
    for row in array:
        for char in row:
            if char == target_char:
                found = True
                break
        if found:
            break
    return found

# 示例用法
array = [['a', 'b', 'c'], ['d', 'e', 'f'], ['g', 'h', 'i']]
target_char = 'e'
result = search_char_in_2d_array(array, target_char)
print(result)  # 输出：True

import numpy as np

def search_char_in_2d_array(array, target_char):
    np_array = np.array(array)
    found = np.any(np_array == target_char)
    return found

# 示例用法
array = [['a', 'b', 'c'], ['d', 'e', 'f'], ['g', 'h', 'i']]
target_char = 'e'
result = search_char_in_2d_array(array, target_char)
print(result)  # 输出：True
